Step-by-step explanation:
Probability of choosing a purple jelly bean, eating it, and then choosing a blue jelly bean is; 12/95
We are given the contents of the package as;
Red jelly beans = 4
Green jelly beans = 2
Purple jelly beans = 8
Blue jelly beans = 6
Total number of jellybeans = 4 + 2 + 8 + 5 = 20
Probability of selecting a purple jelly bean and eating it = 8/20
After picking one, we are left with 19 jellybeans. Thus;
Probability of picking a blue jelly bean and eating it = 6/19
Thus;
Probability of choosing a purple jelly bean, eating it, and then choosing a blue jelly bean = 8/20 × 6/19 = 48/380 = 12/95
