Suppose that 10 transistors are randomly drawn from a box containing 26 good transistors and 4 defective transistors. What is the probability that exactly 9 of the transistors are good?
------------------
Binomial Problem with n = 10 and p(good) = 26/30 = 13/15
-----
P(x = 9) = 10C9*(13/15)^9*(2/15) = 0.3678
