Mark the correct alternative in the following: If A = {x : x is a multiple of 3} and, B = {x : x is a multiple 5}, then A − B is

Philoid · Accepted Answer

A∖ B is the set of elements which are in A but not in B

⇒A∖B is the set of elements which are in A and in B'

⇒A∖ B is the set of elements of A⋂B'

∴A∖B=A⋂B'

=A⋂B ̅
