I will not edit your post - it really bothered me to edit every post.
I will keep your text as is, although it really needs to be edited.
Total people is 8+7 = 15.
(a) both men P(both men) = = = .
(b) both women P(both women) = = = .
(c) of the same sex P(both men) + P(both women) = + = .
(d) of the different sex: the complement to the value of (c) 1 - = .
Solved.
