Poisson process with rate . The distribution of the time R until a claim
is reported is random with P (R r) = G(r) and ER = ⌫ . (a) Find the
distribution of the number of unreported claims. (b) Suppose each claim has
mean µ and variance 2 . Find the mean and variance of S the total size of the
2.57. Suppose N (t) is a Poisson process with rate 2. Compute the conditional
probabilities (a) P (N (3) = 4|N (1) = 1), (b) P (N (1) = 1|N (3) = 4).
2.58. For a Poisson process N (t) with arrival rate 2 compute: (a) P (N (2) = 5),
(b) P (N (5) = 8|N (2) = 3, (c) P (N (2) = 3|N (5) = 8).
2.59. Customers arrive at a bank according to a Poisson process with rate 10
per hour. Given that two customers arrived in the ﬁrst 5 minutes, what is the
probability that (a) both arrived in the ﬁrst 2 minutes. (b) at least one arrived
in the ﬁrst 2 minutes.
2.60. Suppose that the number of calls per hour to an answering service...
