The syllabus is as follows: 1. Basic notions of probability. Sample spaces, events, relative frequency, probability axioms. 2. Finite sample spaces. Methods of enumeration. Combinatorial probability. 3. Conditional probability. Theorem of total probability. Bayes theorem. 4. Independence of two events. Mutual independence of n events. Basic Probability Formulas Complementary events: The complement of event A is everything not in A. Complementary events are mutually exclusive events and together make up the sample space. The probability of the sample space is one. Probability gives a measure of how likely it is for something to happen. It can be defined as follows: Definition of probability: Consider a very large number of identical trials of a certain process; for example, flipping a coin, rolling a die, picking a ball from a box (with replacement), etc. Statistics Facts, Formulae and Information. mathcentre is a project offering students and staff free resources to support the transition from school mathematics to university mathematics in a range of disciplines. www.mathcentre.ac.uk.

Probability is a number between 0 and 1 that says how likely something is to occur: 0 means it's impossible. 1 means it's certain. The higher the probability of a value, the higher its frequency in a sample. More specifically, the probability of a value is its relative frequency in an infinitely large sample.

The formula computes the probability that at least one of the Aievents happens. The probability of getting exactly one of the Aievents is similarly computed by: Xk i=1 Pr(Ai)−2 Xk i
