The number of inclusions in cast iron follows a Poisson distribution with a mean of 2,500 per cubic centimeter. Poisson Distribution (pmf): 1.X e f(x) = P(X = x) = for x = 0,1,2,... (a) Determine the mean and standard deviation of the number of inclusions in a cubic centimeter. (b) Approximate the probability that less than or equal to 2600 inclusions occur in a cubic centimeter. (Hints: use the normal approximation method.) (c) Approximate the probability that greater than...

The number of errors in a sequence follows a Poisson distribution. The average number of errors in 50 members of the sequence is 1.2. (a) What is the probability of exactly three flaws in 150 members of the sequence? (b) What is the probability of exactly one flaw in the first 50 members of the sequence and exactly one flaw in the second 50 members of the sequence? Since this is a Poisson distribution the two parts of the sequences...
