Flaws occur at random along the length of a thin copper wire. Let x represent the random variable that counts the number of flaws in a length of wire and it follows a Poisson's distribution. Suppose the average number of flaws is 2.3 per 1 millimeter. Determine the probability of a) exactly 2 flaws in 1 millimeter of wire; b) at most 2 flaws in 1 millimeter of wire; c) at least 3 flaws in 1 millimeter of wire; d) at least 1 flaw in 2 millimeters of wire.
