Alice walks into a post office with 2 clerks. Both clerks are in the midst of serving
customers, but Alice is next in line. The clerk on the left takes an Expo(λ1) time to
serve a customer, and the clerk on the right takes an Expo(λ2) time to serve a customer. Let T be the amount of time Alice has to wait until it is her turn.
(a) Write down expressions for the mean and variance of T, in terms of double integrals
(which you do not need to evaluate).
(b) Find the distribution, mean, and variance of T, without using calculus.

Use the frequency distribution, which shows the number of american voters (in millions) according to age, to find the probability that a voter chosen at random is in the 18 to 20 years old age range. ages frequency 18 to 20 5.9 21 to 24 7.7 25 to 34 20.4 35 to 44 25.1 45 to 64 54.4 65 and over 27.7 the probability that a voter chosen at random is in the 18 to 20 years old age range is nothing. (round to three decimal places as needed.)
