Question 844599: Let U = {2, 3, 4, 5, 6, 7, 8}, A = {2, 3, 4, 5}, B = {2, 3, 6, 7}, and C = {4, 6, 8}. List all the members of the given set. (Enter your answers as a comma-separated list.)
A ∪ (B ∩ C)
Answer by KMST(5328)   (Show Source):
You can put this solution on YOUR website! The intersection of B and C includes all the elements both sets have in common, and only those elements.
So, B ∩ C = { 6 } because 6 is the only element B and C have in common.
The union of that set with set A includes all the elements of A and it includes 6, and does not include anything else, so
A ∪ (B ∩ C) = {2, 3, 4, 5, 6}
