Question

true or false. {3,5} is a subset of {1,3,5} justify

Answer 1

Hi ,

If A and B are two sets and

Each and every element of set A is an element

set B then A is subset of B .

A = { 3, 5 },

B = { 1 , 3, 5 }

3 € A and 3 € B

5 € A and 5 € B

therefore ,

A is subset of B

I hope this helps you.

Answer 2

A set is called subset of any set if all the elements of the same are elements in the second set

In other words,If A and B are two sets and A is called Subset of B if and only if All the elements of A are also present in B .

Here , A ={ 3 ,5 }

B ={ 1 , 3 , 5 }

Now , 3 ∈ A and also 3 ∈ B

5 ∈ A and also 5 ∈ B .

As all the elements of { 3 ,5 } are present in { 1 , 3 ,5 } .Therefore , { 3 ,5 } is a subset of { 1 , 3 ,5 } .

The given statement is correct .
