Question

let the set A is {1,2,3,} and B is {2,3,4,} the number of elements in A intersection B is​

Answer 1

If set A is {1,2,3} and set B {2,3,4} then the intersection A and B will be of common elements in both of the sets.

Let the intersection set of A & B be C

So set C = {2,3}

Answer 2

$\sf\huge\bold{Answer:}$

Given :

A = {1,2,3}

B ={2,3,4}

To find :

A∩B. [A intersection B]

Solution :

The intersection of two sets is a subset that gives the common values from both sets.

A = {1,2,3}

B ={2,3,4}

Common values in A and B = 2,3

$\huge\mathrm\red{A∩B {}}$

= {2,3}

Let's Know More:-

• There are 4 operations on sets.

1. Union
2. Intersection
3. Difference
4. Complement

• The universal set is the set containing all objects or elements and of which all other sets are subsets.

• The complement of a universal set is an empty set U′ = ϕ.

• The complement of an empty set is a universal set ϕ′ = U.
