SOLUTION: the probability that a car will have a flat tire while driving through a certain tunnel is 0.00006. use the poissan distribution to approximate the probability that among 15000 car

Question 327628: the probability that a car will have a flat tire while driving through a certain tunnel is 0.00006. use the poissan distribution to approximate the probability that among 15000 cars passing through the tunnel at most two will have a flat tire.

The Poisson is given by

In this case,
So, AT MOST 2 means 2 and less. In other words, x=0,1,2.
So, we have to add up the three cases for 0,1,and 2.
