the law of total probability ✔️The probability of an event is the sum of its probability across every
possible condition
permutation ✔️an ordered subset of a set
combination ✔️an unordered subset of a set
discrete ✔️type of random variable that is a set of separate points
continuous ✔️type of random variable that is values on intervals
bernuolli trials ✔️if there are 2 possible outcomes: success and failure, outcomes of different trials are
mutually independent, and p(success)=p is a constant
binomial random variable ✔️x = the number of successes in n bernuolli trials
hypergeometric random variable ✔️x = the number of successes in a random sample of size n drawn
without replacement from the population of size N in which there are r successes
Geometric random variable ✔️x = the number of Bernoulli trials until the first success, y = the number
of failures before the first success
negative binomial random variable ✔️x = the number of Bernoulli trials until the rth success, y = the
number of failures before the rth success
poisson random variable ✔️x = the number of successes in t units of continuous background
