Webb18 aug. 2024 · A contingency table provides a way of portraying data that can facilitate calculating probabilities. The table helps in determining conditional probabilities quite easily. The table displays sample values in relation to two different variables that may be dependent or contingent on one another. Webb13 feb. 2024 · Theoretical probability is the likelihood that an event will happen based on pure mathematics. The formula to calculate the theoretical probability of event A happening is: P (A) = number of desired outcomes / total number of possible outcomes.
