Question

What is subset of{1{1,2,3}

Answer 1

The subset of {1,2,3} is {}, {1}, {2}, {3}, {1,2}, {1,3}, {2,3}, {1,2,3}

• A subset is a collection of elements of a set.
• A set itself is a subset of that set.
• Given set, {1,2,3}
• Number of subsets of a set is given by a formula,
• number of subset = 2^n
• where,  
• n = number of elements present in a set.
• here, there are 3 elements, (1,2,3)
• Therefore, we have,
• 2^3 = 8 subsets.
• 1. {}
• 2. {1}
• 3.  {2}
• 4.  {3}
• 5. {1,2}
• 6. {1,3}
• 7.  {2,3}
• 8. {1,2,3}

Answer 2

The subsets for the given set {1,2,3} are {}, {1}, {2}, {3}, {1,2}, {1,3}, {2,3} and {1,2,3}

Step-by-step explanation:

Given that the set is {1,2,3}

To find the subset for the given set :

Subset : A subset is a collection of elements of a set.

• We know that every set itself is a subset of that set.
• The formula for the Number of subsets of a set is $2^n$

$Number of subsets=2^n$

• Here, n is the number of elements  in the given set.

• Here, there are 3 elements in the given set.
• Therefore, put n=3 we get

• $2^3=8$
• Therefore the given set contains 8 subsets.
• They are {}, {1}, {2}, {3}, {1,2}, {1,3}, {2,3} and {1,2,3}

Therefore the subsets for the given set {1,2,3} are {}, {1}, {2}, {3}, {1,2}, {1,3}, {2,3} and {1,2,3}.
