Let A = {x : x" is a multiple of "3, 5, ...

Let `A = {x : x" is a multiple of "3, 5, lt x lt 19}` and `B={x : x" is a factor of 18"}`.
Find : (i) `A-B`
(ii) `B-A`
(iii) What do you notice ?

Text Solution

Verified by Experts

The correct Answer is:
(i) `{12, 15}`
(ii) `{1, 2, 3}`
(iii) `A-B ne B-A`
`A={6, 9, 12, 15, 18}`
`B={1, 2, 3, , 9, 18}`
(a) `A-B={12, 15}`
(b) `B-A={1, 2, 3}`
(c) `A-B ne B-A`
