Question

If A = (1, 2, 3, 4), B=(3, 4, 5, 6) and C = (1, 2, 4, 6, 7), then find (A-B)U(A-C)?​

Answer 1

Answer:

A-B = ( 1,2)

A-C = ( 3,4)

then (A-B) U (A-C) = { 1,2,3,4}

Answer 2

Answer:

Given

A=(1,2,3,4) , B=(3,4,5,6) and C=(1,2,4,6,7)

(A-B)= (1,2)

(B-C)= (3,5)

(A-B) U(B-C)=(1,2) U(3,5)

=(1,2,3,5)

Hope this helps u.
