(a) What is meant by an experiment? Sample space?

(b) What is an event?

(c) Define the probability of an event E in a sample space S in which all outcomes are equally likely.

(d) What is the probability of the complement of E?

(e) If a coin is tossed three times, what is the probability of getting all heads? At least one tail?

(a)

To explain:

The meaning of experiment, and sample space.

An experiment is any process that gives definite out comes.

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

For example tossing a coin, is an experiment and sample space will be two (

(b)

To explain:

The meaning of event.

(c)

To define:

The probability an event E and sample space S.

(d)

To define:

The probability of the complement of E.

(e)

To find:

The probability of getting all heads, and at least one tail if a coin is tossed three times.
