Question
At a bus stop, there are two buses available (bus numbers 1 and 2). For i = 1, 2,
the waiting time until bus i arrives is denoted by T;, with T independent of T2,
and T; has density function
fr. (t) = X, exp(-1;t), t>0.
You are waiting for either bus 1 or 2 to arrive. Let W denote the waiting time until
you can get on a bus.
ii. Show that E(W) < 1/max(\1, A2). (Hint: You need to work out E(T¡) and
E(T-) first.)
iii. Work out the probability density function of W. (Hint: Find P(W > w) first
for w > 0.)
