Answer:

Let us find the number of subsets and the number of proper subsets for the set {1, 2, 3, 4, 5}.

Explanation:

A set containing n elements has 2n subsets and 2n - 1 proper subset.

The given set {1, 2, 3, 4, 5} contains 5 elements.

So, it has 25 = 32 subsets in all and 31 proper subsets.

You can now find out the number of subsets for the set {1, 2, 3}.

Therefore, the set has 32 subsets and 31 proper subsets.
