Question
Busy people arrive at the park according to a Poisson process with rate λ1=3/hour. Relaxed people arrive at the park according to an independent Poisson process with rate λ2=2/hour. Assume that no other people arrive at the park. During the last 10 minutes, exactly two people arrived at the park. What is the probability that they are both relaxed?
