If we toss a money, toss a dice, or taking the beads, we can’t determine the surface of the cointhat will be appear, which spots of dice that will beappear, and what color of beads that will we get.

In general, the events that will be come out is uncertain and still be a possibility.

The possibility or appearance of an event is called probability.

From previous explanation, we can determine the relative frequency by using this way :
