You can put this solution on YOUR website! B ∩ C = { 11 }
B and C only have the number "11" in it (this number is in BOTH set B and set C)
-------------------------------------------------------
A ∪ (B ∩ C) = A ∪ { 11 } = {7, 8, 9, 10} U { 11 } = {7, 8, 9, 10, 11}
-------------------------------------------------------
Answer: A ∪ (B ∩ C) = {7, 8, 9, 10, 11}
