R.1. If A, B, and C are sets with A- B and B -- C , prove that A -C. (Hint: Recall what it means for two sets to have the same cardinality. Use that to come up with the candidate for the one-to- one function that will map A onto C. You will still need to prove that it's in fact one-to-one and onto.)
