Clinical trials of Nasonex involved a group given placebos and another group given treatments of Nasonex.

If 5 of the 10 subjects are randomly selected for the treatment group, find the probability of getting 5 subjects of the same sex. Would there be a problem with having members of the treatment group all of the same sex?
