We have to find the probability that Isaac will find his first defective can among the first 50 cans.
Then the number of adults follows a geometric distribution, where the probability of success on each trial is p, then the probability that the kth trial (out of k trials) is the first success is

We have to evaluate:

0.0064 is the probability that Isaac will find his first defective can among the first 50 cans.
