Question 1163005
This is looking at 0,1,2 accidents with Poisson parameter 7.4

On the calculator, 2ndVARS C Poissoncdf ENTER (7.4,2), where the 2 is the largest value allowed.  Probability is 0.0219

or P(0)=e^(-7.4)*7.4^0/0!=0.000611
P(1)=0.0045. the above answer *7.4^1/1, which is 7.4
P(2)=0.0167
