Q5 of 162 Page 1

Let U = {1, 2, 3, 4, 5, 6, 7, 8, 9}, A = {1, 2, 3, 4}, B = {2, 4, 6, 8} and C = {3, 4, 5, 6}. Find:

B’

B’ means Complement of B with respect to universal set U.


So, B’ = U – B


U – B is defined as {x ϵ U : x ∉ B}


U = {1, 2, 3, 4, 5, 6, 7, 8, 9}


B = {2, 4, 6, 8}


B’ = {1, 3, 5, 7, 9}
