You can put this solution on YOUR website!
Hits on a personal web site occur quite infrequently. They occur randomly and independently with an average of five per week.
Poission Problem:
lambda = 5
a) Find the probability that the site gets 10 or more hits per week.
I used a TI calculator to get:
P(x>=10) = 1-poissoncdf(5,9) = 0.0318..

b) Determine the probability that the site gets 20 or more hits in two weeks.
Not sure. What is your setup for this?
