Question

A jar contains 10 yellow, 6 red, and 4 green jellybeans. What is the probability of selecting

a yellow jellybean, replacing it, and then selecting a red jellybean?

Answer 1

(p yellow) = 1/2

(p red) = 3/10

Explanation:

Find the total number of jellybeans.

10 + 6 + 4 = 20

Find the probability of selecting a yellow jellybean

(p yellow) = 10/20

reduce by 10

(p yellow) = 1/2

Find the probability of selecting a red jellybean

(p red) = 6/20

reduce by 2

(p red) = 3/10
