Congrats on the wife :)


Here are these:

1. Describe (in words) two different sets of people containing you as a member. Describe (in words) the complement of each set. Describe what people are not in either the original set or the complement set.

I belong to the following two sets: people who kickbox, and people have three jobs.
The complements of these sets are: people who don't kickbox, and people who don't have three jobs.

Since everyone either kickboxes or not, and has three jobs or doesn't, there shouldn't be any people who don't belong either the original set or its complement.


2. Using the same two sets you described in problem 2, describe (in words) the new set formed by joining the two sets together. Is the new set called the union of the original sets, the intersection of the original sets, or neither? Explain.

When we join the two sets together, we come up with the set of people who have three jobs, kickbox, or both have three jobs and kickbox. This is the union of the two original sets, since we are taking elements from each and combining them.


Let me know if you have any questions,
