Question 41887: During a clothing sale, 1/4 of the store merchandise is reduced in price, Find the probability that 3 of 5 randomly-selected shirts have reduced prices. Answer by fractalier(6550) (Show Source):
You can put this solution on YOUR website! I believe this one is done like this...
P(3 of 5 have reduced price) = C(5,3)*(1/4)^3*(3/4)^2 =
10 * 1/64 * 9/16 =
45/512
