Answer:
[tex]0\le P\le 1[/tex]
Step-by-step explanation:
The probability of an event is a number describing the chance that the event will happen.
Definition: The probability of an evant is
[tex]P=\dfrac{\text{Number of favorable outcomes}}{\text{Number of all possible outcomes}}[/tex]
1. An event that is certain to happen (Number of favorable outcomes = Number of all possible outcomes) has a probability of 1.
2. An event that cannot possibly happen (Number of favorable outcomes = 0) has a probability of 0.
3. If there is a chance that an event will happen, then its probability is between 0 and 1.
Thus,
[tex]0\le P\le 1[/tex]
