Question

A jar contains jelly beans that are red, yellow, blue, and purple. Several people reach in and grab handfuls of jelly beans, then collectively tally the number of each color: 15 red, 20 yellow, 12 blue, and 8 purple. If someone pulls out 22 jelly beans, about how many would you expect to be yellow?

A.4
B.20
C.13
D.8

Answer 1

Total jellybeans pulled out: 15 + 20 + 12 + 8 = 55

Proportion of yellow jellybeans: 20 / 55 = 4/11

(4/11) * 22 = 8.

Answer: 8
