11. Given a Poisson process having rate A where A is specified, you will be asked to compute E[X(t1)], E[X (t2)2], and E[X(t3) X(t4)] for specified values of ti, i = 1, 2, 3, 4. 12. Given a Poisson process {N(t), t 2 0} with rate 1, you will be asked to compute some probabilities and conditional expected values associated with this process. For instance, E[N(t) |N(s)]=
