Question 1149773: Using the poisson distribution cloth is woven continously in a textile mill and from experience it is known that an averge of 20 defects occur in each 1,000 ft of fabric. A sample of 100 ft of cloth is taken from the output. What is the probability that it will contain 3 defects?

Would expect 2 defects in 100 ft of fabric, 1/10 of 1000
so want p(3) for Poisson with parameter 2
that is e^(-2)*2^3/3!
or 0.1804
