Binomial in Math

If you have a if you have a fair coin you know the That number one two one and then if you flip it a third time it becomes one three three one And then ifyou flip it a fourth time, yeah So this is actually related to something called Pascal's triangle. It's basically the number of different ways you can get heads and choose k. In math might be a good question: How is this related to binomial? Uh, it is very related. We might get to that eventually.
