Cardinality of a null set
WebA is the set whose members are the first four positive whole numbers B = {4, 2, 1, 3} Let's check. They both contain 1. They both contain 2. And 3, And 4. And we have checked every element of both sets, so: Yes, they are equal! And the equals sign (=) is used to show equality, so we write: A = B Example: Are these sets equal? A is {1, 2, 3} Web1.
