Question

let A={1,2}, B={3,4},C={4,5}, then (A-B)×(B-C) is (a){(1,3),(2,3)} (b){(1,3),(2,3)} (c){(2,3),(2,4)} (d){(1,4),(2,3)}​

Answer 1

Answer

both a and b

Step-by-step explanation:

A-B={1,2}

B-C={3}

so,

(A-B)X(B-A)={(1,3),(2,3)}

Answer 2

A = {1 , 2}B = {3 , 4}

C = {4 , 5}

A − B = {1 , 2}

B − C = { 3 }

(A − B) × (B − C)={(1 , 3) , (2 , 3)}
