WebbIn most cases, you will multiply across the branches to get probabilities. However, you may also want to add vertically to get probabilities. For example, if we wanted to find out our probability of getting HHH OR TTT, we would first calculated the probabilities for each (0.125) and then we would add both those probabilities: 0.125 + 0.125 = 0.250. WebbThe probability calculator multiple events uses the following formula for calculating probability: \text {Probability} = \dfrac {\text {Event}} {\text {Outcomes}} Probability = OutcomesEvent The calculation of probability is initiated with the determination of an event. Every event has two possible outcomes.
