Question

If A={1,2,3},B=null set then find A intersection B

Answer 1

Answer:

null set

Step-by-step explanation:

A= {1,2,3}

B = { }

A intersection B = no common element

= { }

= null set

Answer 2

Answer:

A∩B =  null set = Ф

Step-by-step explanation:

Given,

A={1,2,3},B=null set

To find,

A intersection B

Solution:

Recall the concept:

The intersection of two sets A and B is defined as the set of elements that are common in both A and B. It is denoted by A∩B

A∩B = {x:x∈Aand  x∈B}

Null set(Ф) is the set that has no elements in it

Here the set A ={1,2,3}, B=null set

Since B is a null set, there are not elements in the set B

Hence, there are  no common elements in A and B

Hence, there are no elements  in A∩B, A∩B is a null set

∴A∩B =  null set = Ф
