Preliminary Examination in Discrete Structure

(a)   are intuitively most people to mean a collection of objects that are called elements.

(a)   are that contained the set.

The number of different elements in A is called its (a)   .

Any set that is not finite is an (a)   set.

(a)   is the set of all elements under discussion for possible membership in a set.

A diagram of a set is called (a)   .

(a)   are naturally used to count things.

The term (a)   refers to the fact that each digit in the decimal representation of a number has significance based on its position.

(a)   is the “art of counting”.

The (a)   of A and B (denoted by A⊕B ) is the set of all elements that are in A and B but not in both.
