Poisson Processes. Suppose you have two independent Poisson processes (N1(t), 12 0} and {N2(t), t 0), where Ni(t) has rate λ and N2(t) has rate μ. Label the arrivals from N(t) as "type1" and arrivals from N2(t) as "type 2." Let Z be a random variable that represents the time until the next arrival of either type. What is the distribution of Z? (Justify your answer.) Poisson Processes. Suppose you have two independent Poisson processes (N1(t), 12 0} and {N2(t),...

Let ??1(??) and ??2(??) be two independent Poisson processes with rates ??1 = 1 and ??2 = 2, respectively. Find the probability that the second arrival in ??1(??) occurs before the third arrival in ??2(??). Hint: One way to solve this problem is to think of ??1(??) and ??2(??) as two processes obtained from splitting a Poisson process.
