Probability
Probability is the quantification of the likelihood that an event or a set of events will occur. Using Wolfram|Alpha's broad computational understanding of probability and expansive knowledge of real-world applications of probability theory, you can compute the chances of winning various games driven by random chance, conduct and analyze the experimental outcomes of random trials, visualize and compute the properties of probability distributions and calculate the probabilities of events given a set of conditions.
Compute winnings, analyze bets and determine outcomes for games of chance ranging from the toss of a coin to a game of poker and the draw of your local lottery numbers.
