Math Problem Statement

Please help to solve below question using probability concept.

The probability mountain lion A shows up on a given day is 1/2, the probability that mountain lion B shows up on a given day is 1/3, and the probability that you see more than one lion on a given day is zero. Your friend and you play a game where the first person to see their mountain lion on 3 days (not necessarily consecutive) wins. You pick mountain lion A and your friend picks mountain lion B. What is the probability a winner will be determined before day 5?

Let the probability be expressed in the form of p/q where p and q are relatively prime whole numbers. Answer with the value of p+q.
