Question

what is difference of sets ?​

Answer 1

Step-by-step explanation:

The difference of set B from set A, denoted by A-B, is the set of all the elements of set A that are not in set B. In mathematical term, A-B = { x: x∈A and x∉B} If (A∩B) is the intersection between two sets A and B then, A-B = A - (A∩B)

Answer 2

Answer:

The difference of set B from set A , is denoted by A - B.

It is the set of all the elements of set A that are not in set B.

A-B is equal to A - ( A intersection B )

Eg:

A = { 1,2,3,4 }

B = { 3,4,6,7 }

A-B ={ 1,2 }
