Question 840506: Please help me solve this problem:
In a bottling filling plant, random samples of 9 bottles are chosen on regular intervals and the number of under-filled bottles are identified. Assume that the probability of a single bottle being under-filled is 5%. What is the probability that there will be more than one under-filled bottle in a randomly drawn sample of 9 bottles?

-----------------
Binomial Problem with n = 9 and p(under) = 0.05
-------------------------------
P(more than 1) = 1 - P(none) = 1 - (0.95)^9 = 0.3698
