Substitute n=4 n = 4 into the formula. Web there are 2 options whether it contains 2 or whether it contains 3. For example, if a = {1, 2, 3}, then the number of elements of a = 3. And for the remaining 5 there are 2 5 = 32 ways it may contain any combination of those. Web if a is the given set and it contains n number of elements, we can use the following formula to find the number of subsets. This is similar to subset sum problem. There's no other way to choose combination subsets. {1, 3, 2, 5, 4, 9}, find the number of subsets that sum to a particular value (say, 9 for this example). Web the number of subsets of a set with n elements is 2 n. The subsets of a are { }, {1}, {2}, {3}, {1, 2}, {2, 3}, {3,.
And for the remaining 5 there are 2 5 = 32 ways it may contain any combination of those. Web we are looking for the number of subsets of a set with 4 objects. The subsets of a are { }, {1}, {2}, {3}, {1, 2}, {2, 3}, {3,. Web the solution set must not contain duplicate subsets. Web or in other words, a strict subset must be smaller, while a subset can be the same size. Web the number of subsets of a set with n elements is 2 n. There's no other way to choose combination subsets. Web this is easy to verify. The only possible 2 letter subsets from a, b, c, and d are: \begin {array} {l} {2}^ {n}= {2}^ {4}\qquad \\ \text { }=16\qquad \end {array} 2n. For example, if a = {1, 2, 3}, then the number of elements of a = 3.
