Let X1, X2,..., Xnbe independent and identically distributed exponential random variables with parameter λ .
a) Compute P{max(X1,
X2,..., Xn) ≤ x}
and find the pdf of Y = max(X1,
X2,..., Xn).
b) Compute P{min(X1,
X2,..., Xn) ≤ x}
and find the pdf of Z = min(X1,
X2,..., Xn).
c) Compute E(Y) and E(Z).
