Required information NOTE: This is a multi-part question. Once an answer is submitted, you will be unable to return to this part. Find the cardinality of the set A. A = [0, {0}] Multiple Choice O O O, as neither Ø or (Ø) are valid elements of a set. 1, as the elements Ø and [Ø) are the same. 1, as you count the set containing the empty set as an element, but you do not count the empty set as an element of the set. 2, as the empty set Ø is an element and (Ø), the set containing the empty set, is a second (and different) element.
