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 ii ) ( p intersection Q ) intersection S
​

Answer 1

Answer:

Given P={1,2,5,7,9}

Q={2,3,5,9,11}

R={3,4,4,7,9}

S={2,3,4,5,8}

P intersection Q=all elements that are common between P and Q={2,5,9}

Now let p intersection Q be set X

Implies that X intersection S =all elements that are common between X & S= {2,5}

Hence answer =(p intersection q) intersection s

= {2,5}

If there is any problem with my solution please let me know
