Overview

Probability studies chance and uncertainty in random experiments. A random experiment has more than one possible outcome, all possible outcomes are known in advance, and the exact outcome cannot be predicted before the experiment happens. Common examples are tossing a coin, throwing a die, and drawi

Key Concepts

An experiment is an action

An experiment is an action which results in some well defined outcomes. A coin toss, a die throw, or drawing a card are examples.

A random experiment has more than

A random experiment has more than one possible outcome, and it is not possible to predict the exact outcome in advance. All outcomes are known before

A trial is each single performance

A trial is each single performance of a random experiment. One toss of a coin, one throw of a die, or one simultaneous toss of two coins is one trial.

If all outcomes of an experiment

If all outcomes of an experiment have equal chances to take place, they are called equally likely outcomes. Tossing a coin, throwing a die, and drawin

Each outcome of an experiment

Each outcome of an experiment is called an event.

Learning Objectives

  • Understand the meaning of experiment and random experiment
  • Identify a trial as one single performance of a random experiment
  • Recognize equally likely outcomes and events
  • Write all possible outcomes for simple random experiments
  • Find probability using favourable outcomes and total outcomes
