Finding the Number of Subsets of a SetWe have looked only at combination problems in which we chose exactly rr objects. In some problems, we want to consider choosing every possible number of objects. Consider, for example, a pizza restaurant that offers 5 toppings. Any number of toppings ...

13. Let S be a set of 10 elements. We wish to count the number of subsets of subsets of S.More precisely, find the number of pairs (X, Y) such that X C Y C S? C A. 0 B. 211 C. 3^(10) D. 311 E. 4^(10)
Consider finding the number of subsets that do not contain any primes.There are four primes in the set:2, 3, 5, and 7.This means that the number of subsets without any primes is the number of subsets of {4,6,8,9}, which is just 24=16. The number of subsets with atleast ...
