Question

If u = {1, 2, 3, 4, 5, 6, 7, 8, 9)A={2, 3, 5, 7,9}
B = {1, 2, 4,6} verify
(1) AUB = AnB
(2) B-A=BnA = B - (AnB)​

Answer 1

Step-by-step explanation:

1) answer

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

AnB= {2}

2) answer

B-A = {1,4,6}

BnA= {2}

AnB= {2}

B-(AnB) = {1,4,6}

Answer 2

Answer:

given

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

A={2,3,5,7,9}

B={1,2,4,6}

1) AUB = AnB

L.H.S

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

R.H.S

AnB = {2}

L.H.S is not equal to R.H.S

hence not verified

2) B-A =BnA =B -(AnB)

L.H.S

B-A = { 1,3,4,5,6,7,9 }

Midle

BnA = { 2 }

R.H.S

B - (AnB)

(AnB) = {2}

Midle = R.H.S

but L.H.S is not equal
