My attempt
I used negative binomial to solve the problem, however I'm left with a polynomial that is difficult to solve? Is there any other way to approach this problem?
I used the inequality because I'm trying to find the range of p. Since the probability of winning the series for team A is written above, the probability should be more than 0.5 since that would mean it would be at an advantage. The sum of the probabilities that I've written in the image shows the probability that team A can win in 4 games , 5 games, 6 games or 7 games.
Is there a way to solve this polynomial?
