Understanding Independent Events Probability

In probability theory, two events are independent if the occurrence of one does not affect the probability of the other. For independent events, the probability of all events occurring is the product of their individual probabilities.

For example, if you flip a coin twice, the outcome of the first flip does not influence the outcome of the second flip. If the probability of getting heads on a single flip is 0.5, then the probability of getting heads on both flips is 0.5 * 0.5 = 0.25.

This calculator helps you compute the combined probability for any number of independent events. Simply enter the probability of each event, and the tool will calculate the overall probability of all these events happening together.
