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) Content: Sample space, events as sets, unions and intersections.
