Probability — Chapter Summary

A random experiment is an experiment

A random experiment is an experiment in which all possible results are known in advance, but none can be predicted with certainty, and there is equal

The result of a random experiment

The result of a random experiment is called an outcome. A coin toss has two outcomes: Head and Tail. A die has six outcomes: 1, 2, 3, 4, 5, and 6.

The set of all possible outcomes

The set of all possible outcomes of a random experiment is called the sample space and is denoted by S or Ω. Each element of the sample space is calle

For one coin tossed

For one coin tossed, S = {H, T} and n(S) = 2. For three coins tossed, S = {HHH, HHT, HTH, THH, HTT, THT, TTH, TTT} and n(S) = 8. For two dice thrown,

Outcomes are equally likely if none

Outcomes are equally likely if none of them occurs in preference to others. A fair coin and a fair die have equally likely outcomes. If a die is forme
