a Poisson process with rate 4. Suppose that 3/4’s of the calls are made by men,
1/4 by women, and the sex of the caller is independent of the time of the call.
(a) What is the probability that in one hour exactly 2 men and 3 women will
call the answering service? (b) What is the probability 3 men will make phone
calls before 3 women do?
2.61. Hockey teams 1 and 2 score goals at times of Poisson processes with rates
1 and 2. Suppose that N1 (0) = 3 and N2 (0) = 1. (a) What is the probability
that N1 (t) will reach 5 before N2 (t) does? (b) Answer part (a) for Poisson
processes with rates 1 and 2 .
2.62. Consider two independent Poisson processes N1 (t) and N2 (t) with rates
1 and 2 . What is the probability that the twodimensional process (N1 (t), N2 (t))
ever visits the point (i, j )? 100 CHAPTER 2. POISSON PROCESSES Chapter 3 Renewal Processes

and exponentially distributed. The lack of mem...
