Question:
As for Property 3 of the exponential distribution, let T1, T2, . . . , Tn be independent exponential random variables with parameters 1, 2, . . . , n, respectively, and let U min{T1, T2, . . . , Tn}. Show that the probability that a particular random variable Tj will turn out to be smallest of the n random variables is P{Tj U}
