Answer 29

Read this article. You will findwhat you seek. My first venn diagram image and the answer obtained from that is incorrect. You must put the two sets together and take out repeats.

yeah, well can't help you there. The answer should be what agrees with that wiki article.

Answer 32

you can never trust Wiki...

Answer 33

Well, I'm as worthy of trust as wiki. The wiki math articles have yet to fail me. If you don't want to read wiki, just google union set theory and see if what you get disagrees.

Answer 34

yeah aint nobody got time for that so thank you for your help!
