Question

If A=(prime numbers less than 20) and B=(whole numbers less than 10) then (A-B) n (B-A)

Answer 1

Answer:

(A-B)n(B-A)=(2,3,5,7)

Step-by-step explanation:

BECAUSE,

A=(2,3,5,7,11,13,17,19)

B=(0,1,2,3,4,5,6,7,8,9)

the symbol n(intersection) represents common elements between A and B

the common elements in both the sets are 2,3,5,7

so,(A-B)n(B-A)=(2,3,5,7)
