Question

complement of a set B is denoted by​

Answer 1

Answer:

The relative complement of A in B is denoted B ∖ A according to the ISO 31-11 standard. It is sometimes written B − A, but this notation is ambiguous, as in some contexts it can be interpreted as the set of all elements b − a, where b is taken from B and a from A.

Answer 2

The complement of the set B is denoted by B' or U - B

Given :

The set B

To find :

The complement of the set B

Solution :

Step 1 of 2 :

Write down the given set

Here the given set is B

Step 2 of 2 :

Find the complement of the set B

U is Universal set

We know that for any set A the complement of B is denoted by U - B or B' and defined as

U - B

= B'

= { x ∈ U : x ∉ B }

For example ,

Let us consider

U = { 1 , 2 , 3 , 4 }

B = { 1 , 3 }

Then U - B = B' = { 2 , 4 }

Hence the complement of the set B is denoted by U - B or B'
