Consider the sets below.U = {x | x is a real number}A = {x | x is an odd integer}R = {x | x = 3, 7, 11, 27}Is R ⊂ A?
A
yes, because all the elements of set A are in set RB
yes, because all the elements of set R are in set AC
no, because each element in set A is not represented in set RD
no, because each element in set R is not represented in set A
