Geometric probability · Darts
How far from the bullseye
A point is chosen uniformly at random inside a disc (think of a dartboard) of radius 1. What is its expected distance from the center?
Answer with an expected value. First lock in a gut guess with an 80% range, then solve it properly, then watch a simulation settle on the truth.
