Note:
B ∩ (A U C) means set B intersected with set A union with set C.
Set A = {0, 1, 2, 3, 4, 5}
Set B = {6, 7, 8, 9, 10}
Set C = {2, 4, 6, 8, 10}
Find B ∩ (A U C).
I should find A U C first.
A U C = {0, 1, 2, 3, 4, 5} U {2, 4, 6, 8, 10}
A U C = {2, 4}
B ∩ (A U C) = {6, 7, 8, 9, 10} ∩ {2, 4}
B ∩ (A U C) = null set or empty set
I think this is correct.

Yes you should but the union is {0,1,2,3,4,5,6,8,10}

Yes, my bad. A U C means set A union or united with set C. All the elements of set A united with all the elements of set C.
I then need to find find B intersected with A U C.
B ∩ (A U C) = {6, 7, 8, 9, 10} ∩ {0, 1, 2, 3, 4, 5, 6, 8, 10}
B ∩ (A U C) = {6, 8, 10}
I hope this is correct now.

Great news! I do my best to show math work.
