I sample p uniformly from [0,1] and flip a coin 100 times. The coin lands heads with probability p in each flip. Before each flip, you are allowed to guess which side it will land on. For each correct guess, you gain 1$, for each incorrect guess you lose 1$. What would your strategy be and would you pay 20$ to play this game?
