PROBABILITY - Coggle Diagram
PROBABILITY
The probability of an event is the ratio of the number of ways an event can happen to the total number of outcomes in the sample space.
-
If an event E can not occur, then P(E)=0
If an event E is certain to occur, then P(E)=1
The sum of the probability of success and the probability of failure for any event is always equal to 1. So P(E) + P(E') = 1

Compound Events
In general, a compound event consists of two or more simple events. Tossing a dice is a simple event; but tossing two dices or coins is a compound event.
