You can put this solution on YOUR website! 50 ovens were shipped to a store. 4 of the 50 were defective. What is the probability that exactly 2 of the first 5 sold are defective?
--------------------------
Binomial with n=5 and p = 4/50 = 0.8
--------------------------------------
Probability of 2 defective = P(x = 2) = 5C2*0.8^2*0.2^3 = 0.0512
