A printing company's bookbinding machine has a probability of 0.75 for producing a perfect book. This machine used to bind three books together.
1) Find the probability that all three books are perfect books?
----
Binomial Prob. with n = 3 and P(perfect( = 0.75
P(x = 3) = 0.75^3 = 0.4219
--------------------------------
2) Find the probability that at least one of the books are perfect?
P(at least one perfect) = 1 - P(all are defective)
----
= 1 - 0.25^3
----
= 0.9844
