ST111 Probability A
ST1116 Probability (Part A)
Introductory description
This module runs in Term 2 and is a core or listed optional module for some degree courses (primarily in Mathematics and Computer Science) and is also available as an unusual option to students on nonlisted degrees. You may be interested in this module if you have taken the prerequisites and wish to take ST112 Probability B so that you can take further statistics modules.
Prerequisites: MA131 Analysis I AND MA132 Foundations (or equivalent)
Postrequisites: ST112 Probability B, ST104 Statistical laboratory, ST202 Stochastic Processes, ST220 Introduction to Mathematical Statistics
This module is not available to students who have their home department in Statistics, who take an equivalent module. Students who are considering transferring to a course in Data Science, Mathematics & Statistics or MORSE at the end of their first year should take this module.
Module aims
To lay the foundation for all subsequent modules in probability and statistics, by introducing the key notions of mathematical probability and developing the techniques for calculating with probabilities and expectations.
Outline syllabus
This is an indicative module outline only to give an indication of the sort of topics that may be covered. Actual sessions held may differ.
 Experiments with random outcomes: the notions of events and their probability. Operations with sets and their interpretations. The addition law and axiomatic definition of a probability space.
 Simple examples of discrete probability spaces. Methods of counting: inclusionexclusion formula and multinomial coefficients. Examples including the birthday problem and coupon collecting.
 Simple examples of continuous probability spaces. Points chosen uniformly at random in space.
 Independence of events. Conditional probabilities. Simpsonâ€™s paradox. Bayes theorem.
 Binomial probabilities. The law of large numbers, Poisson and Gaussian approximations and their applications.
Learning outcomes
By the end of the module, students should be able to:
 Understand and apply in simple situations the law of large numbers, Poisson and Gaussian approximations for the Binomial distribution.
 Model simple experiments with random outcomes using mathematical probability.
 Compute probabilities by counting sample points or calculating areas/volume.
 Understand the concepts of conditional probability and independence.
