~~~~~~~~~~~~~~~

5 + 7 = 12 people.


In all,  C%5B12%5D%5E4 = %2812%2A11%2A10%2A9%29%2F%281%2A2%2A3%2A4%29 = 495 combinations are possible of 12 people taken 4 at a time.


It is the full size of the space of events in this problem.


Of them,  C%5B5%5D%5E2%2AC%5B7%5D%5E2 = 10*21 = 210 quadruples consists of two men and two women: they are favorable quadruples in this problem.


THEREFORE, the probability under the problem's question is


    P = favorable%2Ftotal = 210%2F495 = 14%2F33 = 0.4242... = 0.4242 = 42.42%   (rounded).    ANSWER

Solved.
