Example: A = {1,2,3} list out all the subsets of A. Solution: 1. We know that empty set Æ is a sub set of any set. 2. Every set is a subset of itself so A is a subset of A. 3. {1} 4.{2} 5.{3} 6.{1,2} 7.{2,3} 8.{1,3}
Observing the above example , If there are n elements in a set the number of subsets of that set is 2^{n}. Directions: List all the subsets and write the number of subsets for the following questions. Also write at least ten examples of your own.
