Question

A bowl contains 27 lemon jelly beans and 13 orange jelly beans. You choose a jelly bean at random and eat it. You then choose another jelly bean. What is the probability in decimal that both jelly beans are orange.

Answer 1

Probability first one is orange:
13/27+13=13/40

probability second one is orange=13-1/27+13-1=12/39

both times:
13/40*12/39=0.1 or 10%

Answer:
The probability to get orange both times is 0.1 or 10%
