Question 1011772: 14. If calls to your cell phone are a Poisson process with a constant rate l=2 calls per hour, what�s the probability that, if you forget to turn your phone off in a 1.5 hour movie, your phone rings during that time? How many phone calls do you expect to get during the movie?
Answer by Boreal(15235) (Show Source): You can put this solution on YOUR website!
Expect 3 calls in a 1.5 hour movie.
Probability (0)=e(-3)*3^0/0!=e^(-3)=0.0498
The probability of not zero; i.e., ringing, is 0.9502.
