problem

Jude repeatedly flips a coin. If he has already flipped nn heads, the coin lands heads with probability 1n+2\frac{1}{n+2} and tails with probability n+1n+2\frac{n+1}{n+2}. If Jude continues flipping forever, let pp be the probability that he flips 3 heads in a row at some point. Compute ⌊180p⌋\lfloor 180 p\rfloor.
Plain-text mathematical notation (without MathML)
Jude repeatedly flips a coin. If he has already flipped n heads, the coin lands heads with probability (1)/(n+2) and tails with probability (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 ⌊180p⌋.
Original LaTeX notation
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 $\lfloor 180 p\rfloor$.
