You can put this solution on YOUR website!
If the names are taken out one by one out of a hat containing all 30 names,
and are written in order on a list, there are
30%2A29%2A28%2A27%2A26%2A25 possible lists.
With just the names of the 11 men, we can make only
11%2A10%2A9%2A8%2A7%2A6 of those lists.
As a fraction of all the possible lists, that is
11%2A10%2A9%2A8%2A7%2A6%2F%2830%2A29%2A28%2A27%2A26%2A25%29=22%2F28275
It really does not matter how the names are randomly selected.
In only 22%2F28275 of the cases there would be only males selected.
The probability is
22%2F28275= approximately0.0007781 or 0.07781%.
It can also be stated as the probability is 1%3Ax one in x.
22%2F28275=1%2Fx --> x=28275%2F22= approximately1285
There is a 1 in 1285 probability of selecting only men.
