CALCULUS Understanding Its Concepts and Methods

Probability

A random experiment is an activity or process whose outcome cannot be predicted.

The sample space is the set of all possible outcomes of an experiment.

An event is a subset of the sample space.

The probability of an event is a number between 0 and 1 that can be thought of as the fraction of times that the event will occur if the experiment is repeated many times.

Numbers which depend on the outcome of an experiment are called random variables.

A random variable that can take any value in an interval is called a continuous random variable.
