In problem 1 the question is they must be the same sex that means either male or female there can either 4 male or female and in problem 2 the question is persons of both sexes that means both sexes are included here so here possibilities because we have to include both genders
Thank you mam🥹🙏
Thankyou mam

But why did you use possibilities in problem 2
Kindly clarify
