This is for union and intersection. I need help.
#11-20: Find the following sets.
U = {1,2,3,4,5} A = {1,2,3} B = {5}
11) A’ = {4,5}
12) B’ = {1,2,3,4}
13) ∪ = {1,2,3,5}
14) ′ ∪ ' = {1,2,3,4,5}
15) ∩ = {
16) ′ ∩ ′ = {4}
17) ′ ∩ = {
18) ∩ ′
19) ′ ∪
20) ∪ ′

Problem 11) Start with set U = {1,2,3,4,5} and cross off 1,2,3 to be left with A' = {4,5}. We basically erase everything found in set A. You have the correct answer. Nice job.

Problem 12) Start with U = {1,2,3,4,5} and erase '5' to be left with {1,2,3,4}. So B' = {1,2,3,4}. You are correct here as well.

I can't help with the other problems since either letters, numbers or symbols are missing. Please make a new post and provide those updates.
