Probabilities of draws without replacement

A history class is compromised of 4 female and 7 male students. If the instructor of the class randomly chooses 6 students from the class for an overall exam, what is the probability that 2 female students and 4 male students will be selected? Round your answer to 3 decimal places.

Tom K.

Fellow Tom gave a correct solution. Another method is to plug in values into the hypergeometric distribution (select 2 females in a sample of 6 when 4 females in the population of 11); the computer, of course, does the same calculations as those mentioned by Tom S.; for example, in Excel, one would use =HYPGEOMDIST(2,6,4,11)
