Question 1033895: A company claims that 99% of its cereal boxes have at least as
much cereal by weight as the amount stated on the box.
At a quality control checkpoint, one box out of a random sample of ten
boxes falls short of its stated weight. What is the probability of this
happening due to chance variation in box weights?

Binomial Problem with n = 10 ; p(not standard) = 0.01
------
P(x = 1) = 10C1*(0.01)*(0.99)^9 = 10*(1/100)*0.9135 = 0.0914
