Question 1118172: Keith�s Florists has 10 delivery trucks used mainly to deliver flowers and flower arrangements. Of these 10 trucks, 5 have brake problems. A sample of five trucks is randomly selected. What is the probability that two of those tested have defective brakes? (Round the final answer to 4 decimal places.)

numerator is 5C2*5C3, because there are 5C3 ways to choose the three without brake problems.
This is 10*10/252 or 0.3968
