Probability distribution
Karten in diesem Stapel (6)
- 1Discrete Probability Distributionapplicable to the scenario where the set of possible outcomes is discrete, such as a coin toss or a roll of dice
- 2Continuous Probability Distributionapplicable to the scenarios where the set of possible outcomes can take on values in a continuous range (e.g., real numbers), such as the temperature on a given day
- 3Binomial distributionBinomial Formula. Suppose a binomial experiment consists of n trials and results in x successes. If the probability of success on an individual trial is P, then the binomial probability is:
b(x; n, P) = nCx * P^x * (1 - P)^n - x
or
b(x; n, P) = { n! / [ x! (n - x)! ] } * P^x * (1 - P)^n - x - 4Hypergeometric DistributionHypergeometric Formula. Suppose a population consists of N items, k of which are successes. And a random sample drawn from that population consists of n items, x of which are successes. Then the hypergeometric probability is:
h(x; N, n, k) = [ kCx ] [ N-kCn-x ] / [ NCn ] - 5Negative Binomial DistributionNegative Binomial Formula. Suppose a negative binomial experiment consists of x trials and results in r successes. If the probability of success on an individual trial is P, then the negative binomial probability is:
b*(x; r, P) = x-1Cr-1 * Pr * (1 - P)x - r
