Answer to Question 1

The Poisson computes probabilities for occurrences of events over some interval.
The Poisson distribution is affected only by the mean , whereas the binomial is affected by sample size n and probability p.
The Poisson distribution has discrete values from 1, 2, 3, . . . with no upper limit. A binomial distribution has discrete values from 1, 2, 3, to n; that is, the upper limit of values is n.

Answer to Question 2

1 ) The random variable x is the number of occurrences of
an event over some interval.
2 ) The occurrences are random.
3 ) The occurrences must be independent of each other.
4 ) The occurrences must be uniformly distributed over the
interval being used.
