Hi, I have this problem 1. The problem statement, all variables and given/known data In telephone network, an average number of failures during a month for one telephone owner is 8. What is the probability that some telephone owner will experience more than 4 failures? 3. The attempt at a solution I have no idea what distribution should I use to model this problem. So far I've come up with binomial distribution with probability of individual event 8/k, where k is number of connection the telephonist will make during a month. But that seems really odd to me... Could someone help please? Thank you.
