Question: Given that x is a random variable for which a

Given that x is a random variable, for which a Poisson probability distribution provides a good approximation, use Table III in Appendix A to compute the following:
a. P(x ≤ 2) when λ= 1
b. P(x ≤ 2) when λ= 2
c. P(x ≤ 2) when λ = 3
d. What happens to the probability of the event {x ≤ 2} as λ increases from 1 to 3? Is this intuitively reasonable?
