Exercise 4. Each of Alice and Bob flips a fair coin for $n$ times, with the $2n$ coin flips being independent. (a) Let $p \in [0, 1]$ be the probability that Alice gets more heads in her $n$ flips than Bob's $n$ flips. Show that the probability that Alice and Bob get the same number of heads is $1 - 2p$. (b) Alice now flips one more fair coin. Using part (a), show that the probability that Alice gets more heads in her $n + 1$ flips than Bob's $n$ flips is $1/2$.
