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

marbles, of which 2 are red.

So, the probability of picking a red marble is

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

x=17

step-by-step explanation:

solve 3x-24=x+10

then that makes it 2x=34 because you subtract an x from both sides to get rid of the one on the right, and then you add 24 to both sides to get rid of the 24 on the left

divide by both sides by 2 to get your answer so that you can get your answer
