Description: Aims:
To provide a solid foundation in discrete probability theory that will facilitate further study in probability and statistics.

Learning Outcomes:
After taking this unit the students should be able to:
* Apply the axioms and basic laws of probability using proper notation and rigorous arguments.
* Solve a variety of problems with probability, including the use of combinations, permutations and standard discrete probability distributions.
* Perform common expectation calculations.
* Calculate marginal and conditional distributions of discrete random variables from joint distributions.
* Calculate and make use of some simple probability generating functions.

Skills:
Numeracy T/F A
Problem Solving T/F A
Data Analysis TF/A
Written and Spoken Communication F (in tutorials)
