2nd one would be 7C5 to pick the males, then 1/2^5 for boys and 1/2^2 for girls = 21/128 (D)

Haven't done this in a while though, but it seemed like binomial probability

Yeah thank you, I realised that I forgot to account for the combinations of boys and girls that could happen, not just the 1 particular set of 5B and 2G in that order.
