All forms of gambling are influenced by random events, such as:
- Shuffled cards being drawn;
- Dice being thrown;
- Wheels being spun;
- Random numbers being generated by a computer;
- A fortuitous set of available scratch and win tickets to choose from; and
- Unforeseen environmental sporting conditions.
Of course, there are probabilities and thus tendencies that can be predicted with relative accuracy over statistically significant periods of time and play. For instance, if a coin is flipped 10 times, it is far more likely to land heads 4 times than it is to land heads only once. However, each flip of the coin is an independent event. Simply put, the coin is a coin – it does not know anything at all. The coin does not know how many times it has been flipped, nor does it know how many times it has already landed heads. Therefore, each time a coin is flipped, the probability that it will land heads is always the same: 50%.
