Question

A={1,2,3,4} B={3,4,5,6} and U={1,2,3,4,5,6} so (AnB)’ = A’uB’

Answer 1

Answer:

A = { 1, 2, 3, 4 } B = { 3, 4, 5 ,6 }

U = { 1, 2, 3, 4, 5, 6 }

LHS : (A ∩ B) = { 3, 4 }

=> (A ∩ B)´ = { 1, 2, 5, 6 }

RHS: A' U B'

=> A' = { 5, 6 }

=> B' = { 1, 2 }

=> A' U B' = { 1, 2, 5, 6 }

LHS = RHS

hence proved
