## Probability calculator

The Probability Calculator computes the probability of one event, based on probabilities of other events. It displays the answer, and writes a report that explains. List of formulas & calculators for statistics & probability functions can be used to perform or verify the results of statistical or probability related calculations. It's the. Multiple Event Probability Calculator. Formulas: Probability of event A occurring P (A) = n(A) / n(S). Probability of event A not occurring P(A') = 1 - P(A). Probability.
To solve a problem input values you know and select a value you want to find. Conditional probability of B, given A: Probability Calculator Frequently-Asked Questions Sample Problems.

P in the diagram above ; for example, the probability of the height of a male student is between 5 and 6 feet in a college. These events would therefore be considered mutually exclusive. There are also Z-tables that provide the probabilities left or right of Z, both of which can be used to calculate the desired probability by subtracting the relevant values. Summary Report Frequently-Asked Questions Sample Problems. Single Event Probability Number of possible outcomes: 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. Use the "Normal Distribution" calculator above to determine the probability of an event with a normal distribution lying between two given values i. Please enter the necessary parameter values, and then click 'Calculate'. P in the diagram above ; for example, the probability of the height of a male student is between 5 and 6 feet in a college. There are two cases for the union of events; the events are either mutually exclusive, or the events are not mutually exclusive. It is an indicator of the reliability of the estimate.
