A four member math team is chosen from the math club which has 3 girls and 5 boys How many different teams made up of 2 girls and 2 boys could be chosen?
We are asked to choose a team of 4 members consisting of two girls and two boys from a math club made up of three girls and five boys.To choose the girls, we leave one out of the team. There are 3 ways to leave one girl off the team.To choose the boys, we can choose any one of the 5 for the first and any one of the remaining 4 for the second. However it doesn't matter the order in which we choose them so we divide by 2. This gives us: 5(4)/2 = 10.This would lead to 3(10) = 30 possible ways to choose the entire team.Note: This is equivalent to 3 choose 2 * 5 choose 2 = 3 * 10 = 30.

How many 3 digit sets of numbers can be formed from the finite set of 12345?
You can make 125 different 3-digit numbers if you're allowed to repeat a digit (for example, 113, or 545), and 60 if you're not. If repetitions are allowed, then there are 5 ways to choose each digit to be 1,2,3,4, or 5, so the total number of ways is 5*5*5 or 125. If no repetitions are allowed, there are 5 ways to choose the first digit, but only 4 ways left to choose the second (for a total of 5*4=20 ways to choose the first two digits), because it can't be the same as the first. Then you have eliminated two choices for the third digit, so there are only 3 ways to choose it, for a total of 5*4*3=60 different 3-digit numbers.
