1) A set is a well-defined group of objects.
2) Elements are the members of a set that share a common characteristic.
3) The set F is a subset of set A if all elements of F are also elements of A.
4) Universal Set (U) is the set that contains all objects under consideration.
5) The cardinality of set A is the number of elements contained in A.
6) Null Set is an empty set.
7) Empty Set is a subset of any set
----------------------
8. A = { a, b, c, d } n(A) = 4
There are four elements in set A (a, b, c and d)
9. B = {2, 4, 6, 8, 10, 12, 14, 16 } n(B) = 8
There are eight elements in set B (2,4,6,8,10,12,14 and 16)
10. C = { apple, orange } n(C) = 2
There are two elements in set C (apple and orange)
