Probability Calculators

Basic Probability is evaluated from Favorable Outcomes, Total Possible Outcomes and Favorable Outcomes. The calculation reports P, P as% and P Complement.

Conditional Probability is evaluated from P - Joint Probability, P - Probability of Event B and P - Probability of Event A. The calculation reports P - Probability of A given B, P as% and P - using Bayes.

Poisson Distribution is evaluated from Average Rate - mean number of events in interval and Number of Events. The calculation reports P - Exactly k events, P - At most k events and P - At least k events.

Exponential Distribution is evaluated from Rate Parameter - events per unit time and Time Value. The calculation reports P - Probability within time x, P - Probability beyond time x and Mean.

Dice Roll Probability is evaluated from Number of Dice, Faces per Die and Target Sum. The calculation reports P, P as% and Total Outcomes.

Lottery Odds is evaluated from Lottery Game, Pool Size and Numbers to Pick. The calculation reports Jackpot Odds, Probability and Expected Value per $1 ticket.

Coin Flip Probability is evaluated from Number of Flips and Desired Number of Heads. The calculation reports P, P and P.
