We know that if we have five as a subset, there is 1 combination. 5C5. 4 as a subset, leaves us with 5 combinations... 5C4. Notice how we are working with combinations in the problem. We …
SOLUTION: In algebra, what do they mean by subset?
A subset of another set is a version of a set containing less elements than the original set, though technically speaking every set has as one of its subsets itself. For example, let a set be the …

You can put this solution on YOUR website! From the condition, in this group there are 50*0.28 = 14 persons who have flue shots done; and the rest 50-14 = 36 persons have no it.
SOLUTION: Of all theses sets which ones are proper subsets {}- {a}
A proper subset must be strictly contained, therefore must exclude at least one element of the original set. The empty set is a proper subset of any non-empty set. So: If the original set was …
