QUESTION 2 Suppose the random variables x and y are independent and both uniformly distributed in the interval [0, 1]. Define the random variable z = |x - Y| (the absolute value of X minus Y). Then, the probability density function (PDF) of 7 is given by: Of(z) = 32, 05251 Of(z) = 2(1-2). 05:51 01 (2) = /(1-2), 05251 1 (2) I m 03:1
