Discrete Random Variables

Defining variables that take on distinct values and calculating their probability distributions.

Key Questions

  1. 1What is the difference between a simple average and the expected value of a random variable?
  2. 2How does the variance of a distribution measure the 'risk' or 'uncertainty' of an outcome?
  3. 3Why must the sum of all probabilities in a discrete distribution always equal exactly one?
