0 means there is no chance of something happening. You cannot have less than no chance of something happening. So a probability cannot be less than 0.

Can a probability be more than 1 or less than 0?

No. A probability of 1 means something will definitely happen. There cannot be a greater certainty than that, so probability cannot be greater than 1. 0 means there is no chance of something happening. You cannot have less than no chance of something happening. So a probability cannot be less than 0.


Which is not a possible vaule for a probability?

Probability value can only be real number between 0 to 1, therefore, it cannot be greater than 1 or less than 0 or a complex number.


When probability is less then 0 what happen?

Probability can not be less than 0 or greater than 1. A probability of 0 means there is no possibility whatsoever of an event occurring. A probability of 1 means that the event is guaranteed to occur no matter what.


Why can't probability be less than 0?

Because probability is measured from zero to one, where zero means something cannot happen and one meaning it will definitely happen. This can also be looked at as there being a 0% chance or 100% chance of it happening. So obviously there can not be less of a chance than it definitely not happening, so it cannot be less than zero.


Why probability always lays 0 to 1?

0 represents that is will never happen. It means that there is no probability that it will happen. 1 represents that is is certain to happen. You cannot be more certain than definitely certain, and something cannot be less probable than not at all.


Why the probability can never be 1 or less than 0?

Probability of 0 is impossible, and 1 is certain. So, probability must be between 0 and 1, inclusive.


Can the value of probability be less than zero?

No. Probability must be between 0 and 1.


Can the probability be more than 1 or less than 0?

No, all probabilities are given from a scale of 0 to 1. 0 represents 0% and 1 represents a 100% probability.


Are fractions and probability the same?

NO, but that is a great question since probability is often expressed as a fraction. Here is the difference. If P(x) is the probability that even x happens, this value must be between 0 and 1. So fractions such as 1/2 or 2/1112 are all fine. Many fractions, such as 4/3 cannot be a probability since they are greater than one. Similarly, -1/2 cannot be a probability value since it is less than 0/


Can probability be less than 0?

No, it must be a number in the interval [0, 1].


What can a probability number be larger than?

Larger or equal to 0 but less than or equal to 1


Does something that can never happen have a probability of 0?

Yes, a probability of 0 is something that cannot happen.


Why 1.34 cannot be the probability of some event?

1.34 cannot be the probability of an event because the range of possibility is 0 to 1. 0 is an impossible event and 1 is a certain event. There cannot be a possibility higher than certain so 1.34 is not possible.


Given a standardized normal distribution with a mean of 0 and a deviation of 1 what is the probability that Z is less than 1.51?

From the related link, you can read directly the probability that Z is less than 1.51 is 0.9345.


What are Synonyms of probability from likely to least likely?

certainty (no doubt), probability or likelihood (greater than 50% chance), possibility (greater than 0% but less than 50% chance)


What is the probability that an event cannot happen?

It is 0.


Which of the following cannot be the probability of an event?

There is insufficient information in the question to properly answer it. You did not provide the list of "the following". Please restate the question. However, by definition of probability, a probability less than 0 (the event will never happen) or greater than 1 (the event will always happen) is impossible, so maybe that answers your question.


What is an event with a probability greater then 0 but less than half?

There are many such events. The probability of throwing a 1 or 2 on one roll of a die, for example.


Suppose z has a standard normal distribution with a mean of 0 and a standard deviation of 1. the probability that z is less than 1.15 is?

probability is 43.3%


A probability can be no larger than what and no smaller than what?

A probability can be no larger than 1 and no smaller than 0.


Are the probability values always greater than or equal to 0 or less than or equal to 1 or all positive numbers?

Probability values are never negative and are always between 0-1 according to the definition Probability of A= Number of outcomes classified as A/Total number of possible outcomes


What is an event that has a probability of 0?

It is something that cannot happen.


What is a probability of 0 which means the event has to happen?

If the probability of an event is zero then that event cannot happen


Why do you use probability?

We use probability to determine if something is likely to happen or not. If the probability is that the incident will definitely happen, then that probability figure is 100% or 1, while if the incident definitely cannot happen the probability figure is 0% or 0; every other possible probability lies somewhere between 0 and 1 (or 0% and 100%).


Why probability is greater than 0 less than 1?

Probability is defined in such a way that 0 (or 0%) means that something is impossible to happen, and 1 (or 100%) means that the event is inevitable. Anything in between means that it MAY happen. Anything outside that range doesn't make sense.
