Guys please Help me solve these two set equation:
1) Let U= {1, 2, 3 ,4, 5, 6}, A= {1, 2, 3, 4}, B= {3, 4, 5,6}, C= {4, 5, 6}
Find (B∪A)’ ∩C
2) Let U= {x: ∈xN, x is even, and 3 ≤ x < 6}
Find n(∪).
---------------------------------------------------------
Let me correct this
2) Let U= {x: x ∈ N, x is even, and 3 ≤ x < 6}
Find n(∪).
The solution is n(∪) = 1. (There is only one number, one element in this set. It is x = 4).
