    PROBLEM 2 Two teams A and B play a soccer match. The number of goals scored by Team A is modeled by a Poisson process Ni(t) with rate l1 = 0.02 goals per minute, and the number of goals scored by Team B is modeled by a Poisson process N2(t) with rate 12 = 0.03 goals per minute. The two processes are assumed to be independent. Let N(t) be the total number of goals in the game up to and...
