The set of all possible out comes tossing a two coins is .

The set of all possible out comes throwing a die is .

Then the set of all possible out comes, when tossing a two coins and throwing a fair die is

The number of all possible out comes are 24.

The number of ways that can occur tossing a two coins and throwing a die is .

All the events are equally likely events.

So the probability of happening of any event is considered as .

The probability of  for equally likely outcomes is defined as and it is denoted by .
