D = {Odd numbers divisible by 2}.
Find: n(A ∪ D)
State true or false for the following. Correct the wrong statement.
If B = {1, 5, 51, 15, 5, 1}, then n(B) = 6.
Verify n(A ∪ B ∪ C) = n(A) + n(B) + n(C) – n(A ∩ B) – n(B ∩ C) – n(A ∩ C) + n(A ∩ B ∩ C) for the following sets
A = {1, 3, 5}, B = {2, 3, 5, 6}, C = {1, 5, 6, 7}
