## Math Forum: Ask Dr. Math FAQ: Probability by mathforum.org

The study of probability helps us figure out the likelihood of something happening. For instance, in the question about the dice, you must figure out all the different ways the dice could land, and all the different ways you could roll a seven. Suppose we have a jar with 4 red marbles and 6 blue marbles, and we want to find the probability of drawing a red marble at random. In our problem, the sample space consists of all ten marbles in the jar, because we are equally likely to draw any one of them. The sample space is a set consisting of all the possible outcomes of an event (like drawing a marble from a jar, or picking a card from a deck).

The probability of the occurrence of an event is always one minus the probability that it doesn’t occur. Given the only two events that are possible in this example (picking a red marble or picking a blue marble), if you don’t do the first, then you must do the second. I will draw a red one second (given that you have already drawn a blue one)? But suppose we want to know the probability of your drawing a blue marble and my drawing a red one?

When we have an event made up of two separate events with the word and, where the outcome of the second event is dependent on the outcome of the first, we multiply the individual probabilities to get the answer. Well, after you draw a blue, there are 9 marbles left and 5 of them are blue, so for me the probability will be 5/9. For instance, when you roll a pair of dice, you might ask how likely you are to roll a seven. Note that when you’re dealing with an infinite number of possible events, an event that could conceivably happen might have probability zero. In this case we know that all outcomes are equally likely: any individual marble has the same chance of being drawn. Because each probability is a fraction of the sample space, the sum of the probabilities of all the possible outcomes equals one.

That is, given this example, the probability of picking a red marble plus the probability of picking a blue marble will equal 1 (or 100 percent). What is the probability that you will draw a blue one first?

When you draw the first marble, there are 10 marbles in the jar of which 6 are blue, so your probability of drawing a blue one is 6/10 (60 percent) or 3/5. How about the probability of my drawing a blue marble too?

Math 10 Provincial Review Sample A Question 11 | Duration 2 Minutes 19 Seconds

Euclid’s postulates, indeed, could be thought of as those assumptions that were necessary and sufficient to derive truths of geometry, of some of which we might otherwise already be intuitively persuaded.

Let angle(h, k) be an angle in a plane [alpha] and a’ a line in a plane [alpha]’ and let a definite side of a’ in [alpha]’ be given. Then there exists in the plane [alpha]’ one and only one ray k’ such that the angle(h, k) is congruent or equal to the angle(h’, k’) and at the same time all interior point of the angle(h’, k’) lie on the given side of a’. And there are going to be more of them in larger volumes of space. The reality of space thus would default to the question of the nature of the reality of virtual particles.

Therefore empty space, a void, and so space itself is an unnecessary hypothesis. The answer is simply that there is a geometrical difference between left and right but not between top and bottom. Why space would be this way is a good question also, but it is a difference that makes for physical differences in the world. But here this is going to be treated like a thought experiment, where the mirror will hold the image and we can move around and consider what is actually seen from only one point of view. Given those parameters, we can imagine how the pair of images will look if we stand behind the object being reflected, and can look around it. We see a similar effect if we go around behind the mirror; and if the mirror both catches the image and is transparent, we now see both images in their correct orientation. We may think of the reversal of the image in a mirror as a kind of rotation, but real rotation in these images is of the viewpoint of the viewer. The produces the same effect and the flip from right to left. This means that the transition to a mirror image, from left to right, is accomplished by any rotation through a dimension at right angles to a two dime nsional object (or a surface). This deeply shook the physics world but nevertheless seemed to pass unnoticed among philosophers talking about space.

In implicit agreement with this, people often think that scale physically doesn’t make any difference. Once the kids are shrunk, they would rapidly lose body heat and die of hypothermia — small mammals like mice have elevated metabolisms that compensate. There is an absolute and a relative sense in which this is true. Scale is literally one of the differences, and a major one, between an elephant and a mouse. Similarly, if we floated in our cube at right an amoeba, or galaxies (as we see here), its scale would become apparent. Leibniz cannot be excused from involvement with this argument, for he himself said that, if all bodies in the universe doubled in size overnight, we would notice no difference the next morning [cf.

This is an ambiguous challenge, since it might mean that the linear dimensions of all bodies would double, or that the actual volume of all bodies would double.

On the other hand, a correspondent has pointed out that the proposal is also ambiguous about what happens to the mass. Or are we talking about a body that increases proportionally in mass also? But either way, whether we conserve the mass or scale it up, the result would be both noticeable and dangerous, since a larger body of the same mass or a larger body with scaled up mass will be physically different in either case from the smaller body.

Only a relation to some other figure or body would define anything about it. There need not even be a claim to truth, just the notion that we are going to do it this way and see what happens. There exist at least three points that do not lie on a line. There exist at least four points which do not lie in a plane. Of any three points on a line there exists no more than one that lies between the other two. It’s full of virtual particles that have real physical effects — particularly that they mediate the transmission of the forces of nature. And virtual particles, of course, rely on the principle that we can steal energy from nothing as long as we return it in a certain length of time — which looks like a fudge on the principles of the conservation of energy and of mass. Motion or position cannot be detected in relation to space itself, since space itself represents no object. Therefore, spatial relations are symmetrical relations among objects that are equivalent and do not exist apart from objects. And we also must note that not all optical transformations work this way.

Of course, the way these images are presented is not quite right. Looking towards the mirror, we are looking in one direction, but looking through the mirrow towards the image, we are seeing things from the opposite direciton. The flip from top to bottom is something we can see if a mirror is lying on the floor, or we see things reflected in the water of a lake. If mirrors flipped things top to bottom as well as left to right, this would actually accomplish two left-to-right flips, which would cancel out.

Organic chemistry, however, did little to dent the conviction of physicists that handedness would not exist at the fundaments of nature. The solar system could be an atom in some larger kind of matter. But for there to be physical differences of scale, as occur in these cases, there must be a physical difference between different volumes of space. A cubic meter of water, if contained, will simply sit there. The mass can be identical, and the relative arrangement unchanged, but the actual volume will make for very different densities. With their differences in size and mass, they simply cannot have the same structure.

Is the mass conserved and thus will remain the same as the body doubles (in size or dimension)?

Of course, changing the mass at all contradicts the premise that we are only talking about space and its relative size.

That is because as a linear dimension increases, volume increases as the cube of that dimensio n. But, at different scales, our actual bodies would function very differently, whether they retained the same mass or whether they had subtantially more mass.

Sometimes it is difficult toknow the statistics are there if you do not see them on thecomputer. Yes, the predominant units are all still metric, althoughcosmologists exploring the earliest instants after the big bangoften use units of planck time instead, but this of course is stillbased on the metric system. By using the inverse opperation, you divide 186 to 6 and you would get 31. To solve, you have to make each side of the ration equal, like an even scale. When there are an odd amount of numbers: the median is the middle number. The word ‘sum’ is used colloquially for any simple arithmeticalcalculation, but in mathematics a ‘sum’ is properly the result ofadding two or more numbers.

Can you name the 3-dimensional shape with 20 congruent triangles as faces?

An example could be the 20-sided die, if you have seen those before. Math allows us to isolate one or a few features such as the number, shape or direction of some kind of object. The traditional answer is probably something like dimensions of a city or agricultural field or aircraft runway. The thickness of a human hair (say 100 micrometers) is approximately 6×10^-8 miles. Would the mass be the same in a sealed cup of water?

If you mean, does sealing the cup change themass, then no it does not change the mass of the water, though thesealing material would add its own mass to the total. If the midsegment of a triangle is 5x plus 3 and the base is 27 what is the measure of the midsegment?

L contains the m coins which are known to be either good or light. It ain’t so much the things we don’t know that get us in trouble. To number a book from 1 up to its last page took 552 digits.

First, we may remark that the time spent by the boats at their destination is irrelevant, as long as they both spend the same amount of idle time between each encounter. This answers the question posed, but we may also be curious about the speeds of the respective boats. The boat which had travelled 720 yd at the first meeting has therefore travelled three times that (2160 yd) at the second meeting. Well, this is indeed an ingenious way to present the solution, but we’d rather use the “cut-and-dried rules of mathematics” to discover the solution to all similar problems.

He does the same thing again so there are now 4u in the stash. H contains the h coins which are known to be either good or heavy. In a “seven-eleven” (7-11) store, a customer selected four items to buy. So, one (and only one) of the amounts, say a, is a multiple of 79. He said that 98% of the world’s population would not be able to solve it (there are no tricks, just pure logic). In a street, there are five houses, painted five different colors.

The five homeowners each drink a different kind of beverage, smoke a different brand of cigarette and keep a different pet. In other words, the solution is unique for each of the two possible left/right numbering conventions and these two solutions are trivially related by exchanging only addresses 4 and 5. As this boat has then travelled the width of the river plus 400 yd, the river is thus shown to be 1760 yd wide. No ingenuity is required to solve these and, in most cases, ingenuity does not even help much. The speed of the slower boat is (w/a-1) times the speed of the faster one. He may now start his final journey with 4u: he walks 1d (using 1u) and picks up 1u at the stash (3u remain), so he may carry 4u, walk another day and leave 2u in a second stash, before returning to the first stash where he picks up the remaining 3u. He picks up the 2u that were stored there to walk away with 4u, which is enough to complete the trip (since the second stash is 4d away from the goal).
