i need A and C from Problem 1. I also need A and C from Problem 2 using discrete math.

Problem 1: Two dice are rolled at once: a) How many outcomes give the sum of 4 ? b) How many outcomes give the sum of 7 or the sum of 11 ? c) How many outcomes have at least one die showing 2 ? Problem 2: Suppose there are 10 roads from Oz to Mid Earth and Five roads from Mid Earth to Fantasy Island a) How many routes are there from Oz to Fantasy Island passing through Mid Earth? b) How many round-trips are there of the form Oz-Mid Earth-Fantasy Island-Mid Earth-Oz? c) How many round trips are there of the form Oz-Mid Earth-Fantasy Island-Mid Earth-OZ in which on the return trip we do not reverse the original route from Oz to Fantasy Island/
