A two-horse race is about to take place. Horse A's finishing time X is uniformly distributed between 3 and 8 minutes. Horse B's finishing time Y has a uniform distribution conditional on X, as follows: 4 x fx₁x (y|x) = for ≤ y ≤2x 7x 4 a. Find the pdf of Y (HINT: define first fxy and the joint sample of X and Y). b. Find fxy(xy), the conditional pdf for X given Y. C. Are the event S=X ≤ Y and the random variable Y independent, i.e. is P(S|Y=y) = P(S)? d. What is the probability that the winner wins by less than 1 minute? e. Find the probability that the winning time is less than 6 minutes.
