Problem Statement

Adi the Baller is shooting hoops, and makes a shot with probability pp. He keeps shooting hoops until he misses. The value of pp that maximizes the chance that he makes between 35 and 69 (inclusive) buckets can be expressed as 1a\frac{1}{\sqrt{a}} for a prime aa and positive integer bb. Find a+ba+b.
