Probability

There are ten possible events: that the spinner shows one of the number from 1 to 10.

The probability of each of these events is the same and equals 1/10, 0.1 or 10%

Yes.

The probability that a spinner with N sides stops on 2 particular numbers in two spins in 1 in N2. It does not matter what the two numbers are, since the two spins are sequentially unrelated.

Well they are independent events so it is the probability of getting a correct answer multiplied by the probability of getting a correct answer on the second question.

Short Answer: 1/5 times 1/5=1/25

A person shares their birthday with at least nine million different people around the world.

Because 3/6 of the sides on a number cube have even numbers, the probability of rolling even on one number cube is 1/2(equivalent of 3/6). But since you're rolling twice, you multiply the probability of one by itself (therefore rolling 2 number cubes). So:

1/2x1/2=1/4

The probability of rolling an even number when a number cube is rolled twice is 1/4, 25%, or 1 out of 4.

true

No, it is continuous.

On a fair 50-50 coin, the chance of you getting heads 3 times in a row is .5 * .5 * .5 which is 12.5%

Getting exactly 3 heads out of any number of coin flips involves:

(Number of Flips!/ [6 * (N-3)!]) * (.5^3)* (.5^(n-3))

well lets do the math.

1 dice has a 6:1 odd of getting each number. lets say we get a 2 so that was 6:1. the dice you can get for higher than 6 are

1 6

2 5

3 4

4 3

5 2

6 1

each has a 12:1 chance. the dice that meet the condtion are 2 5 and 5 2 so 12:2 or 6:1

For this answer we must leave Answers.com and travel through another dimension -- a dimension not only of sight and sound but of mind. A journey into a wondrous land whose boundaries are that of imagination. That's a signpost up ahead: your next stop: the Twilight Zone!

The episode was called "A Penny for Your Thoughts" (Season 2, episode 25 staring Dick York)

The Opening narration of that episode goes as follows:

Mr. Hector B. Poole, resident of the Twilight Zone. Flip a coin and keep flipping it. What are the odds? Half the time it will come up heads, half the time tails. But in one freakish chance in a million, it'll land on its edge. Mr. Hector B. Poole, a bright human coin, on his way to the bank.

The man flips a coin, it lands on edge, and he discovers that he's mysteriously become telepathic. At the end of the episode, he knocks the coin over and the telepathy goes away.

In reality, mathematicians have tried to figure this out as have physicists. The answer depends on the exact size and width of the edge of the penny, and many other factors. One this is for sure, Rod Serling was not far off when he guessed one in a million.

Nickels have a larger chance of landing on their edge since they have a larger edge and probability of an American nickel landing on edge is approximately 1 in 6000 tosses by one source. The work is not all shown and I don't believe it has been duplicated.

So I don't think there is an exact answer to your question, but the probability certainly is somewhere between 0 and a number very close to 0. It is statistically insignificant.

I now return you to an area we call Answers. com|WikiAnswers.

It is 1.17

Yes.

0

Prob(Exactly 9 Heads) = 0.0269

Prob(At least 2 Heads) = 0.0327

Prob(At most 8 Heads) = 0.9673

There are many ways to measure distance in math. Euclidean distance is one of them.

Given two points P1 and P2 the Euclidean distance ( in two dimensions, although the formula very easily generalizes to any number of dimensions) is as follows:

Let P1 have the coordiantes (x1, y1) and P2 be (x2, y2)

Then the Euclidean distance between them is the square root of

(x2-x1)2+(y2-y1)2 .

To understand some other ways of measuring "distance" I introduce the term

METRIC. A metric is a distance function. You put the points into the function (so they are its domain) and you get the distance as the output (so that is the range).

Another metric is the Taxicab Metric, formally known as the Minkowski distance.

We often use the small letter d to mean the distance between points.

So d(P1, P2) is the distance between points. Using the Taxicab Metric,

d(x, y) = |x1 - x2| + |y2 - y2|

Normal dice have six surfaces, and there is a one in six chance of rolling any specific surface. Only one surface has a number less than 2 (which is the number 1). So it's one chance in six, or approximately 17%.

1/6 = 16.67%
