Unit 7 - Discrete Probability Distributions

Unit Objectives
Prior Knowledge:
  • Statistics and probability 
By the end of this unit students should be able to:
  • Understand the concept of discrete and continuous random variables and their probability distributions
  • Understand and use probability density functions
  • Find expected value (mean), mode, median, variance and standard deviation
  • Solve problems involving random variables
  • Solve problems using the binomial distribution, its mean and variance.
  • Solve problems using the Poisson distribution, its mean and variance.
