Why does the probability of an event have to be between 0 and 1?

Probabilities are expressed as ratios, or more accurately, fractions. If an event will probably occur 1 time in 10 trials, its probability is 1/10, or 0.1. If the event happens every time (10 in 10, for example), the probability is 10/10 = 1.0. You can never have more than n occurrences in n trials. Conversely, if the event never occurs in 10 trials, its probability is 0/10 = 0.0. An event cannot occur fewer than 0 times. This is why the lower and upper bounds of all probabilities are 0 and 1, respectively.

Can an event E have a probability of -1?
No; probability is between 0 and 1 inclusive.
Limitations of probability?
From 0 to 1 or between an event not happening and an event that will happen
Can the probability of an outcome be greater that one?
No. The probability of an outcome (or event) is always a number between 0 and 1.
Is probability always a fraction?
Only when an event is probability to happen between a range of 1 to 0 then it is a fraction.
The change that a given event will occur usually expressed between the number 0 will not and 1 the event will occur?
The chance that a given event will occur that is usually expressed between the numbers 0 and 1 is known as probability.
Can an event E have a probability of -1?
No; probability is between 0 and 1 inclusive.
Is 0 a possible probability?
Yes. The probability of an event is a number between 0 and 1 (or the equivalent 0% and 100%).
Limitations of probability?
From 0 to 1 or between an event not happening and an event that will happen
What probability of a possible event?
A value that is between 0 and 1.
What is the probability that an event will definitely occur?
If the event will definitely occur, then its probability is 1.Not asked, but answered for completeness sake - if the event will definitely not occur, then its probability is 0. All probabilities lie between 0 and 1, inclusive.
What compares the probability of an event occurring to the probability that it will not occur?
If the probability of an event occurring is p, then 1-p represents the probability of the same event not occurring. The value of p must lie between 0 and 1.
What does it mean for an event to have a probability of 1?
Probability is on a scale of 1 to 0 and 1 is that .an event will certainly happen whereas 0 is that an event will not happen
Is probability always a fraction?
Only when an event is probability to happen between a range of 1 to 0 then it is a fraction.
Can the probability of an outcome be greater that one?
No. The probability of an outcome (or event) is always a number between 0 and 1.
Can -1.5 be the probability of an event?
No. The probability of an event ranges from 0 (the event will not happen) to 1 (the event will happen).
What do you mean by probability?
Probability is a measure of the expectation that an event will occur or a statement is true. Probabilities are given a value between 0 (will not occur) and 1 (will occur).[1] The higher the probability of an event, the more certain we are that the event will occur.
The chance that a a given event will occur usually expressed between the number 0 will not and 1 the event will occur?
