    P = {{{C[26]^4/C[41]^4}}}


The formula says that the probability is the ratio of the number of quadruples(4 women) taken from 26 women
to the number of all possible quadruples of 4 persons selected from 26+15 = 41 person.


{{{C[26]^4}}} = 14950

{{{C[41]^4}}} = 101270


P = {{{14950/101270}}} = 0.1476.     <U>ANSWER</U>
