Answer:

The number of subsets that can be created from the set {1, 2, 3} is:

8

Explanation:

We know that for any set with n elements.

The total number of subsets is given by the formula:


Total\ number\ of\ subsets=2^n

The collection of all the subsets of a set is also known as a Power set.

Here we have a set as: {1,2,3}

i.e. n=3

(There are 3 elements in the set)

Hence, the total number of subsets that can be created by this set will be:


2^3=2* 2* 2=8

The power set of this set is given by:


Power\ set=\{\ \phi,\ \{1\},\ \{2\},\ \{3\},\ \{1,2,3\},\ \{1,2\},\ \{1,3\},\ \{2,3\}\}
