1. The problem statement, all variables and given/known data Two experiments are to be performed. The first can result in any one of m possible outcomes. If the first experiment results in outcome number i, then the second experiment can result in any of ni possible outcomes, i=1 2, ..., m. What is the number of possible outcomes of the two experiments? 2. Relevant equations The generalized form of the basic principle of counting comes to mind. 3. The attempt at a solution Ok, I was thinking something like m*n^(i) or something along those lines.My prof said this is a very easy problem, so could it just be m*n or m*n*i or something? I'm a bit confused.
