problem

Barry picks infinitely many points inside a unit circle, each independently and uniformly at random, P1,P2,…P_{1}, P_{2}, \ldots Compute the expected value of NN, where NN is the smallest integer such that PN+1P_{N+1} is inside the convex hull formed by the points P1,P2,…,PNP_{1}, P_{2}, \ldots, P_{N}. Submit a positive real number EE. If the correct answer is AA, you will receive ⌊100⋅max(0.2099−|E−A|,0)⌋\lfloor 100 \cdot \max (0.2099-|E-A|, 0)\rfloor points.
Plain-text mathematical notation (without MathML)
Barry picks infinitely many points inside a unit circle, each independently and uniformly at random, P₁,P₂,… Compute the expected value of N, where N is the smallest integer such that P_(N+1) is inside the convex hull formed by the points P₁,P₂,…,P_(N). Submit a positive real number E. If the correct answer is A, you will receive ⌊100⋅max(0.2099−|E−A|,0)⌋ points.
Original LaTeX notation
Barry picks infinitely many points inside a unit circle, each independently and uniformly at random, $P_{1}, P_{2}, \ldots$ Compute the expected value of $N$, where $N$ is the smallest integer such that $P_{N+1}$ is inside the convex hull formed by the points $P_{1}, P_{2}, \ldots, P_{N}$. Submit a positive real number $E$. If the correct answer is $A$, you will receive $\lfloor 100 \cdot \max (0.2099-|E-A|, 0)\rfloor$ points.
