Describe whether the following statements are true or false and explain. A. If n(A)<n(B), then A is a proper subset of B. B. If n(A) is less than or equal to n(B), then A is a subset of B. C. If A is a proper subset of B, then n(A)<n(B). D. If A is a proper subset of B, then n(A)is less than or equal to n(B). I say that the answer to A. is false but I'm not sure about the other ones.
