. In--------------------------------- form, the set is represented by describing the common characteristics of all members using symbols.

Two sets A and B are called ----------------- sets if they have no common member.

Two sets are called ----------------sets if they have at least one common member and none of them is a subset if the other set

•The ------------------------ of two sets A and B is a set which  consists of all members of A or B or Both

the ----------------of two sets A and B is a set which consists of common members of A and B

•A set which contains all possible members of a given situation or discussion is called the -------------------------- set

•If U is a universal set and set A is its subset, then U-A is called the ------------------------- of set A and is denoted by A’.
