Question

team a has 4 male and 5 female players, team B has 5 male and 4 female players. 2 players are chosen from each team (total of 4). in how many ways can the players be selected if AT LEAST one of them is a female

Answer 1

What do you know about combinatorics? The easier way with these kind of "at least" questions is to find the total number of possibilities and subtract the possibilities which can't happen (in this case, the number of ways to select a team with no females).

Answer 2

so (9C2 x 9C2) - (4C2 x 5C2)?

Answer 3

Yes, I believe that is correct. There is a similar question posted on this website: http://tinyurl.com/bt9gndw
