-Assumes a ﬁnite number of values,where the probability for each value is equal.If there are x values,the
probability for each one is 1/x.
-The probability of x 'successes' out of n tries,where each event has the probability p.
-A series of Bernoulli trials,with constant probability,which take X trials to get the ﬁst success.This distribution is
Negative Binomial Distribution
-A generalization of geometric distribution,in which x is the number of trials required to acquire r successes.This
distribution is memory-less.(This distribution can essentially be taken to be the sum of r geometric distributions.)
-A set of N objects contains K objects classiﬁed as successes,N-K objects classiﬁed as failures.n objects are
