Question

if p={1,2,5,7,9},Q={2,3,5,9,11}, R={3,4,5,7,9} and S={2,3,4,5,8}, then find I)(PUQ)UR ii)(QUs)UR​

Answer 1

Answer:

1) 1,2,3,4,5,7,9,11

2)2,3,4,5,7,8,9,11

Answer 2

Step-by-step explanation:

solution:-

PUQ={1,2,5,7,9}U{2,3,5,9,11}

={1,2,3,5,7,9,11}

i)(PUQ)UR={1,2,3,5,7,9,11}U{3,4,5,7,9}

={1,2,3,4,5,7,9,11}

Again,

QUS={2,3,5,9,11}U{2,3,4,5,8}

={2,3,4,5,8,9,11}

ii)(QUS)UR={2,3,4,5,8,9,11}U{3,4,5,7,9}

={2,3,4,5,7,8,9,11}
