If I = {a, b, c, e, f, g}, A = {b, e, f) and B = {a, b, c}, then find A' ∩ B'?

If I = {a, b, c, e, f, g}, A = {b, e, f) and B = {a, b, c}, then find A' ∩ B'?

Explanation

Step 1: Find A'

A' = I - A = {a, b, c, e, f, g} - {b, e, f} = {a, c, g}.

Step 2: Find B'

B' = I - B = {a, b, c, e, f, g} - {a, b, c} = {e, f, g}.

Step 3: Find A' ∩ B'

A' ∩ B' = {a, c, g} ∩ {e, f, g} = {g}.
