    there are 6 girls, you need to choose 3 of them, where order does not count. thats 6 choose 3 . that will be your numerator (the favorable event). the denominator is the total possible 3 positions from the set of 10 kids, so thats 10 choose 3

    part b) you want 1 boy and 2 girls. there are 4 boys in total, so you want to choose 1 boy. This is 4 choose 1. now for each one of these choices you want to pick 2 girls out of 6 ( 6 choose 2). so multiply them 4 choose 1 * 6 choose 2 . this is your numerator. the denominator is like before 10 choose 3
