When tossing a coin, it is more likely to land on the same side as it was tossed. The frequentist approach was used by great personalities in the history of probability and statistics such as the Comte de Buffon or Karl Pearson.

The Bayesian approach uses the degree of uncertainty we have about a process and the observations made contribute to improving that uncertainty. This is the approach used in a recent study carried out by more than 50 researchers from the Netherlands and allows us to trust the coin to break the same tie.
