Question

Hi. I am stuck on this question.

List the subsets of the set:
{5, 10, 15}

What am I supposed to be doing? I just do not understand whatsoever. My book also was not much help, it just said the definition and not how to solve it.

Answer 1

The subsets consist of all sets with any or all of the elements of the set. And don't forget to include the empty set. A set of n elements has 2^n subsets. For this set, they are
Ø
{5}, {10}, {15}
{5,10}, {5,15}, {10,15}
{5,10,15}
