We all know when you flip a coin the chances of hitting either heads or tails is 50/50, and yet we also realize that this does not mean that once you have flipped "heads" then the next flip has to come "tails." This is because each flip is independent of previous flips, and previous flips have no bearing on future events. We don't know why they happen, or how long they will last.

Since this is the case, we can look around us and see trends taking place. If you've ever been to a casino then you have surely witnessed a trend take place. Most professional gamblers will tell you to always look for and follow the trends, never bet against them. Or maybe it was at the roulette table when you saw 10 red numbers in a row. But what we do know for sure is. Perhaps it was at the craps table with a hot shooter, hitting one point number after the other. Trends can be a very good thing or a very bad thing depending on what side of the bet you are on.

This means that if you manage to flip 100 heads in a row, the chances of the next coin coming heads is still 50/50.
