I think this is a combination (b/c order really doesn’t matter). But anyway you just multiply from 7 to 4. You know that only one person can hold one job and there are 7 kids. When someone is elected president there are only 6 kids, and so and so on. so 7*6*5*4=840. So there are 840 ways to slect the four offices you have outlined.

Vote to give the president authority to appoint all lower offices. Then elect the presiden. It should make for a very interesting campaign
