Hi...we are doing this now in math. Our teacher insists on writing every possible outcome in a random experiment, which is proposterous. Why write out and literally count something that is fully calculable? I can get some things pretty well. We'll have questions like "4 coins are flipped" with "what are the chances that there will be at least 2 heads"? Well...we also have some with dice....like rolling two d6's, what are the chances that the sum of the two numbers will be 4-7 inclusive? I know what the answer is, but how would you get it with just math? I think it would invlolve factorials. Please..tell me EVERYthing there is to know about calculating probabilities with a set of so many given outcomes, etc.
