This is what I got: 18C3 * 7C2 + 18C4 * 7C1 + 18C5 * 7C0 = 47,124
Is this right?

The probability of choosing 2 girls at random from group of 25 students of which10 are girls and 15 are boys is:P( 2 girls) = (10/25)∙(9/24) = 3/20 = 0.15 = 15%

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.
If in a group of 30 children there are four times as many boys as girls How many girls are there?
If there are four times as many boys as girls, then the ratio of boys to girls is 4:1. To find the number of girls, divide the total number of children by the sum of the parts of the ratio, which is 4+1. So, there would be 30/5 = 6 girls in the group.
