Question 53
Jude repeatedly flips a coin. If he has already flipped $n$ heads, the coin lands heads with probability $\frac{1}{n+2}$ and tails with probability $\frac{n+1}{n+2}$. If Jude continues flipping forever, let $p$ be the probability that he flips 3 heads in a row at some point. Compute $\lfloor 180 p\rfloor$.
