Overview

Probability measures the chance of an event. Experimental probability comes from repeated trials, while theoretical probability is found by counting favourable outcomes and total possible outcomes when outcomes are equally likely. The chapter builds from simple experiments like tossing a coin and th

Key Concepts

Experimental probability is calculated from actual

Experimental probability is calculated from actual trials using P(E) = Number of trials in which the event happened / Total number of trials. A coin t

Theoretical probability is calculated as P(T)

Theoretical probability is calculated as P(T) = Number of outcomes favourable to T / Number of all possible outcomes of the experiment, when outcomes

Outcomes are equally likely when chances

Outcomes are equally likely when chances of getting them are equal. A fair coin and a fair dice are standard examples.

The sample space is the set

The sample space is the set of all possible outcomes of an experiment. For one coin toss, it is {H, T}. For two different coins tossed simultaneously,

An event having only one outcome

An event having only one outcome in an experiment is called an elementary event. Getting a head in one coin toss is an elementary event; getting a num
