Problem 6 a. Let X and Y be independent identically distributed exponential random variables with probability density function fX(x) = λe^-λx and fY(y) = λe^-λy respectively. Define W = X / min(X, 2Y) Find the p.d.f of W. b. Let fXY(x, y) = { 2e^-(x+y) 0 < x < y < ∞; 0 otherwise } Define Z = X + Y W = Y/X Determine the joint pdf of Z and W. Are Z and W independent random variables?

00:01 Let's all the given questions.
00:02 According to the question, m is equals to 900.
00:07 Sigma is equals to 50.
00:10 P z less than z is equals to 2 .5 percent.
00:15 So it is equal to p z less than z is equal to 0 .025.
00:23 Then we get p that less than minus 1 .96 is equals to 0 .025...
