Beginner Topic 11 of 51 Math for Computing
Probability Basics
Measuring the likelihood of events.
How it works
Probability assigns values in [0,1] to events with P(Ω)=1 and additivity for disjoint events; P(A∪B) = P(A)+P(B)−P(A∩B).
Where it is used
Risk, randomized algorithms.
Common pitfall
Assuming equal likelihood where outcomes are not equally likely.
Where it fits in the course
Probability Basics is topic 11 of 51 in Math for Computing, rated Beginner. It follows Determinants. The next topic is Random Variables.
