Question

Suppose there are 15 jelly beans in a box—3 red, 2 blue, 4 white, and 6 green. A jelly bean is selected at random. What is the probability that the jelly bean is neither red nor blue? (Round your answer to the nearest whole number.

Answer 1

10/15 or 0.66666 or 1

Explanation:

There are 15 jellybeans to choose from. Since we're not looking to pick a red or blue jelly bean we subtract them from 15, so (15 jelly beans) - (3 red + 2 blue jelly beans) = 10 jelly beans. Now we have what we're looking for so we do: 10/15
