Probability Distribution

A function in mathematics that calculates the chances of various outcomes happening in an experiment.

E(x)

The expected value of a random variable, representing the mean or average value the variable takes over a large number of experiments or trials.

  • Compute the average (expected value) and standard deviation for a specified probability distribution.
  • Comprehend and compute probabilities linked to discrete random variables.
