A random right triangle can be constructed as follows. Let X be a random angle whosedistribution is uniform (0, 7/2) i.e X ~is uniform (0, 1) i.e. b~triangle with base b and angle X. Here Y height of the random triangle. Find the probabilitydensity function of height Y.Unif(T/2) and b be a random base whose distributionUnif(1). Here X and b are independent. For each X and b, construct a
