I need some instruction for setting up an equation in a Cardinal Number Formula.
The word problems in this section cunfuse me. I know that i am supposed to sort the information to its designated area on the ven diagram. It is just getting the right number to the right spot that confuses me.
Your questions give me a general idea of what you need me to go over, and hopefully I'll be able to address these issues in our next class.
Your first question isn't specific enough to be answered here. I'm not sure in what context you are trying to set up the equation. However I can say that n(A) is the number of things in set A, n(B) is the number of things in set B, n(A ^ B) is the number of elements that the two sets have in common, and n(A U B) is the number of elements in the set formed by throwing all the elements of A and B into the same set.
