Question

P={1,2,5,7,9} Q={2,3,5,9,11} S={2,3,4,5,8}the find {p intersection Q} intersection. S

Answer 1

Answer:

these is equal to { 2 , 5 } .

Step-by-step explanation:

{ P intersection Q} = { 2 , 5 , 9 }

now

{ P intersection Q} intersection S ={ 2 ,5}

Answer 2

Answer:Qn(S)nR={5}

(QnS) will contain all the elements common to both q and s

so (QnS)={2,5}

(QnS)nR will contain elements common to above set {2,5] and R

so Qn(S)nR={5}
