Calls originate from Dryden according to a rate 12 Poisson process. 3/4 are local and 1/4 are long distance. Local calls last an average of ten minutes, while long distance calls last an average of five minutes. Let M be the number of local calls and N the number of long distance calls in equilibrium. Find the distribution of (M, N). what is the number of people on the line. Will give brainliest answer!
