mayankdevnani · Answer

M' ---- it means that the set which is complemantary to M.
Or the set which is include in U(Universal Set) but not include in M(positive integers)

Mathematically,
$$\large \bf M'=U-M$$

mayankdevnani · Answer

U=positive integers
M=positive odd integers.
So, M'=U-M
M'=(positive integers)-(positive odd integers)

therefore,we get

M'=positive even integers i.e M'={2,4,6,8......}
