How many different teams of 5 children can be chosen from a group of 18 girls and 7 boys?
I figured out the answer: 18+7 = 25, So 25C5 = 53,130 Teams. This assumes there are no sex restrictions on the teams (for example, "teams must include at least one boy and at least one girl"). That would be a lot more complicated, and if that's a factor you'd need to specify exactly what the restrictions are.
How many different teams of 5 children can be chosen from a group of 18 girls and 7 boys if each team must have at least two girls on it?
This is what I got: 18C3 * 7C2 + 18C4 * 7C1 + 18C5 * 7C0 = 47,124 Is this right?
