Question: Given that x is a random variable for which a Poisson probability distribution provides a good approximation, compute the following: LO9 a. P1x 12

Given that x is a random variable for which a Poisson probability distribution provides a good approximation, compute the following: LO9

a. P1x … 12 when l = 1

b. P1x … 12 when l = 2

c. P1x … 12 when l = 3

d. What happens to the probability of the event 5x … 16 as l increases from 1 to 3? Is this intuitively reasonable?
