Let and be independent exponential random variables with rates and respectively. a) let w= . find the distribution of w . start by remembering which of the following is easiest when working with minima: the density, the cdf, or the survival function. b) let c be a positive constant. use the results about exponential random variables in sections 16.1 and 17.2 of the prob 140 textbook to find > without integration. c) use part (b) to find the cdf of .
