Mathematics Set Theory Subsets
Without writing them all out, what is the number of subsets of set A ={king, queen, knight, prince, princess, duke, earl}?
To find the number of subsets of set A, we can use the formula 2^n, where n represents the number of elements in the set. In this case, set A has 7 elements. Therefore, the number of subsets of set A is 2^7, which equals 128.
To find the number of subsets of a set, you can use the formula 2^n, where n is the number of elements in the set. In this case, set A contains 7 elements, so you can calculate the number of subsets by raising 2 to the power of 7:
2^7 = 128
