Question 1163005: The number of traffic accidents that occur on a particular stretch of road during a month follows a Poisson distribution with a mean of 7.4. Find the probability that fewer than three accidents will occur next month on this stretch of road

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
