(i). The mean of X.

(ii). The standard deviation of X.

(b). The number of lightning strikes in a year at the top of particular mountain has a poison distribution with parameter ?=2.9.Find the following.

(i). The probability that in a randomly selected year the number of striking is less than or equal to 5.

(ii). The probability that in a randomly selected year the number of striking is greater than 5.
