The number of emails that I receive from you are independent and arrive at random at an average rate of 2 in any 10 minute period. What is the probability that I receive exactly 4 emails in any hour?
Homework Answers
Average = 2 in any 10 minutes = (2*6) i.e. 12 in every 1 hour
So,
P(X = 4)
= 0.0053
