Topics in Probability

1

1. Basic idea of probability

  • Probability gives a numerical measure of how likely an event is.
  • Experimental probability comes from actual trials and records what happened.
  • Theoretical probability is based on equally likely outcomes and counts favourable outcomes.
2

2. Experimental probability and coin toss data

  • A normal coin tossed 1000 times gave 455 heads and 545 tails.
  • Experimental probability of getting head in that case is 0.455.
  • Buffon, Kerrich, and Pearson all carried out large coin-toss experiments.
3

3. Sample space, elementary events, and mutually exclusive events

  • For one coin toss, the sample space is {H, T}.
  • A single outcome event is an elementary event.
  • Getting a head and getting a tail are mutually exclusive events.
4

4. Complementary, impossible, and sure events

  • The complement of an event E is not E, written as Ē.
  • For any event E, P(Ē) = 1 - P(E).
  • Complementary events are mutually exclusive and exhaustive.
