    Are you looking at how many subsets of 4 things can be made?

    It says classify each number by naming all the subsets in which it is an element... I don't get it

    Ok. So let's try some examples and see if we can find a pattern We have 4 numbers, 1,2,3,4 The way we can group them where 4 is a member is 1,2,3,4 2,3,4 3,4 4 Are there any other way to make subsets of 4 that also contain 4?

    There are two choices for each element (included or not) so in total we have 2^4 = 16 possibilities
