Question
If K = {a, b, d, e, f}, L = {b, c, d, g} and M = {a, b, c, d, h} then find the following:
K ∩ (L ∪ M)
Solution
K = {a, b, d, e, f}, L = {b, c, d, g} and M = {a, b, c, d, h}
K ∩ (L ∪ M)
(L ∪ M) = {b, c, d, g} ∪ {a, b, c, d, h}
= {a, b, c, d, g, h}
K ∩ (L ∪ M) = {a, b, d, e, f} ∩ {a, b, c, d, g, h}
= {a, b, d}
