Defective Transformers In a shipment of 50 transformers, 8 are known to be defective. If 30 transformers are picked at random, what is the probability that all 30 are nondefective? Assume that all transformers look alike and have an equal probability of being chosen.
Round your answer to 6 decimal places.|||Favorable outcomes/All outcomes =
42x41x40...x23/50x49x48x...x31=
42!/22! / 50! / 30! =
I don't have a calculator with C or P button, so you're on you own. I am doing it as a permutation. If you did it as a combination, it would be the same.
