Inclusions are defects in poured metal caused by contaminants. The number of (large) inclusions in cast iron follows a Poisson distribution with a mean of 2.5 per cubic millimeter.

Determine the following:

(a) Probability of at least one inclusion in a cubic millimeter.

(b) Probability of at least five inclsuions in 5.0 cubic millimeters.

(d) Instead of a mean of 2.5 per cubic millimeters, the mean inclusions per cubic millimeter such that the probability of at least one inclusion is 0.95
