When two events occur sequentially, and you want to know how many ways for these events to occur together, you can use fundamental counting principle. And it's something that is very easy to visualize and figure out! Two things I love when doing math.
For example if you have event X that has 2 different outcomes and event Y that has 5 different outcomes, then there are 2*5 different ways for events X and Y to occur together. It doesn't get much easier than that!
You can also use fundamental counting principle when you have more than just two events as well. You just continue the multiplication process. An example would Be event A has 3 outcomes, event B has 6 and event C has 3. The total different ways for outcomes to occur would be 3*6*3.
I think this process is so easy to use and follow. It is very quick too!
