What is the probability that a coin will land on heads and then a coin will land on tails? Take advantage of the WolframNotebookEmebedder for the recommended user experience. In the case where the events are mutually exclusive, the calculation of the probability is simpler: A basic example of mutually exclusive events would be the rolling of a dice, where event A is the probability that an even number is rolled, and event B is the probability that an odd number is rolled. This may seem counter-intuitive, and it is also a classic mistake that casino or lotto players make, but in no case does the fact that an element has been drawn during a previous draw increase or decreases his chances of being drawn in the next draw.
