can someone explain an improper subset and a proper subset to me with examples please!
Say: U =(1,2,3,4,5,6,7,8,9,10). A =(2,4,6,8,10,12) and B = (3,6,9,12)
Improper Subset = A(2,3*)
Proper Subset = A = (2,4)
*3 is NOT a element of A
An improper subset is an empty set or a subset containing all of the elements of the original set
