Hi wonder if someone could point me in the right direction with this problem.

"A basketball coach wishes to estimate probability of success pi of a player based on observing a game. She has no prior knowledge of the player so allocates a flat non-informative prior p(pi)=1, where pi is between 0 and 1. The player scores 6 goals from 6 attempts in the game, derive an expression for the players posterior probability p(pi|y) and find the normalising constant."

Thanks in advance, any help would be appreciated.
