Suppose a bag of marbles has 4 green, 2 red, 5 yellow, 1 brown, and 7 blue marbles. what is the probability of picking a red marble?

Assuming that each marble can be picked with equal probability, we notice that there is a total of

So, the probability of picking a red marble is

In fact, as in any other case of (finite) equidistribution, we used the formula

the square root of what number? if you add that, then someone will probably answer the question.

the answer is 24
