Formula :
Probability = favorable outcome/Total outcome
Total boxes = 2
Probability of picking box A = 1/2
Now, number of dark chocolates in box A = 5
number of milk chocolates in box A = 10
So, total = 5 + 10 = 15
Probability of picking milk chocolate = 10/15
= 2/3
Probability of both events happening = 1 /2 × 2 /3
= 1/3
