SOLUTION: A jury pool consists of 27 people, 18 men and 9 women. Compute the probability that a randomly selected jury of 12 people is all male.

You need to know, how many different sextuples can you combine from 27 people;

then you need to know, how many sextuples can you combine from 18 men;

then relate the second number to the first.



So,  the probability under the problem's question is


    P =  =  =  = 0.010374    ANSWER
