Imagine throwing darts at a circular dart board, B. Let us measure the dart board in units for which the radius of B is 1, so that the area of B is π. Suppose that the darts are thrown in such a way that they are certain to hit a point in B, and that each point in B is equally likely to be hit. Thus, if A ⊂ B, then the probability of hitting a point in A is likely to be hit. Thus, if A ⊂ B, then the probability of hitting a point in A is

![]()
Define the random variable X to be the distance from the center of B to the point that is hit.
(a) What are the possible values of X?
(b) Compute P(X ≤ 0.5).
(c) Compute P(0.5
(d) Determine and graph the cumulative distribution function of X.
(e) [Optional—for those who know a little calculus.] Determine and graph the probability density function of X.
