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.


The chance that a given event will occur usually expressed between the number 0 and 1?

The chance that a given event will occur is typically expressed as a probability, which is a number between 0 and 1. A probability of 0 means the event will not occur, while a probability of 1 means the event will definitely occur. Probabilities between 0 and 1 give us the likelihood of the event happening.


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.


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.


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


What is the probability to an event that can never happen?

The probability of an event that can never happen is 0. This means that there is no chance or possibility for that event to occur, making it impossible within the given context or conditions. In probability theory, events are assigned values between 0 and 1, where 0 indicates impossibility and 1 indicates certainty. Thus, a never-happening event is represented by a probability of 0.


What is the minimum value of a probability?

The minimum value of a probability is 0. This indicates that an event is impossible and will not occur. Probabilities range from 0 to 1, where 0 signifies impossibility and 1 signifies certainty. Any probability value between 0 and 1 represents varying degrees of likelihood for an event to occur.
