Probability calculations determine the chance of a specific event occurring. This calculation factors in the number of positive events with respect to the total number of possible results. When you ...

For any event that has multiple outcomes with different probabilities, it can be helpful and illustrative to construct a chart or diagram of the possible outcomes. Tree diagrams are a useful example ...

Two events are independent if the probability of the first event happening has no impact on the probability of the second event happening. For example, the probability of rolling a 6 on a die will not ...
