Question 15 • Grade 7 Mathematics

A package contains 4 red, 2 green, 8 purple, and 6 blue jelly beans. What is the probability of choosing a purple jelly bean, eating it, and then choosing a blue jelly bean?

Answer
A
3 over 25
B
1 over 400
C
12 over 95
D
1 over 380

Explanation

There are 20 jelly beans total. The probability of choosing purple first is 8/20; after eating it, 19 jelly beans remain, including all 6 blue ones, so the probability of blue next is 6/19. Multiply: (8/20) × (6/19) = 48/380 = 12/95. Therefore, the probability is 12 over 95, choice C.
