Probability Tips

  • Discrete random variables are things we count
  • A discrete variable is a variable which can only take a countable number of values
  • Probability mass function (pmf) is a function that gives the probability that a discrete random variable is exactly equal to some value.
  • Continuous random variables are things we measure
  • A continuous random variable is a random variable where the data can take infinitely many values.
  • Probability density function (PDF), or density of a continuous random variable, is a function that describes the relative likelihood for this random variable to take on a given value
  • Bernoulli process is a finite or infinite sequence of binary random variables
  • Markov Chain - stochastic model describing a sequence of possible events in which the probability of each event depends only on the state attained in the previous event
