Question

Prove that (i) A B or (A- B) U (B – A) = (A UB) - (A ∩B)

Answer 1

Answer:

1. ABor(A-B)U(B-A)=(AUB){An B}

Step-by-step explanation:

1. let x€{A-B}U{B-A}
2. =×€{A-B Or^€(B-A}

×€AbutX€Bor×€Bbutx€Aorx€B

x€(AUB)

X€{AUB}-{A-B}

Since sincere here represent aribitrany element of the set {A-B}U{B-A}

Thus{A-B}U{B-A} {AUB}-{An B}
