If J= {x € Z|0 < x < 4}, then J has exactly 9 subsets. Let E = {even integers} and O = {odd integers}. Then, |E| > |O|. %3D Let F = {x € R | x5 is defined }. Then, F is a proper subset of R. If G = {y € R|y= cos x; x € R}, then, G is an improper subset of R. Let P = {x €R|x² = 16 } and Q = {x €R| |x| = 16}. Then P = %3D %3D = Q. %3D
