Question

How to solve the 3rd one?

Answer 1

Answer:

iii.) if a and b are any two sets then verify using Venn diagram or otherwise

Answer 2

Step-by-step explanation:

let A={1,3, 5,6} and B ={2,4,9} such that A-B = A which implies that elements present in A but not in B is equal to A

A- B = {1,3,5,6} -{2,4,9}={1,3,5,6}=A

then A intersection B = null becUse there are no common elements. if there is any common element then A-B removes that element in the result and we will not get A.
