Key Topics to Revise

1

1. Core Ideas and Basic Setup

  • Probability is treated as a function of outcomes in the axiomatic approach.
  • A random experiment has a sample space S made of all possible outcomes.
  • Events are subsets of the sample space.
2

2. Properties of Conditional Probability

  • If F has occurred, then S and F both have conditional probability 1 given F.
  • Union under conditioning follows the addition rule with overlap removed.
  • For disjoint events A and B, the conditioned union simplifies to a sum.
3

3. Multiplication Rule of Probability

  • The multiplication rule is obtained from conditional probability.
  • It gives probability of simultaneous occurrence of events.
  • For two events, both forms P(E)P(F|E) and P(F)P(E|F) are valid when the required probabilities are nonzero.
4

4. Independent and Dependent Events

  • Independent events are events whose occurrence does not affect each other.
  • Two equivalent descriptions are used: conditional probability form and product form.
  • Dependent events are simply events that are not independent.
