The document discusses calculating probabilities based on a Poisson distribution with a mean of 4.5. It includes specific probability queries such as p(x = 1), p(x < 1), p(x > 1), and p(x 1). The document specifies rounding the results to four decimal places as needed.

1. Assume a Poisson distribution with = 4.5 . Find the following probabilities. a. X = 1 b. x < 1 c. X
> 1 d. X 1 a. P ( X = 1 ) = (Round to four decimal places as needed.)
