The most the probability of an event occurring can be is 1 which means the event has a 100% probability of happening. But 2 is greater than 1 so it cannot be a probability. . Finally, 5/3 is not a probability for the same reason that 2 is not a probability. It is greater than 1. . Hope this helps you understand probability a little better.
Which of the following values cannot be a probability?
What numbers Cannot be a probability? -1 and -0.5 cannot represent probabilities because a probability cannot be negative. 4.2 cannot represent a probability because it is greater than one. 0.6, 0.888, 0, and 0.39 can represent probabilities because they are between zero and one, inclusive.

What are the basic rules of probability?
- Probability Rule One (For any event A, 0 ≤ P (A) ≤ 1)
- Probability Rule Two (The sum of the probabilities of all possible outcomes is 1)
- Probability Rule Three (The Complement Rule)
- Probabilities Involving Multiple Events
- Probability Rule Four (Addition Rule for Disjoint Events)
- Finding P (A and B) using Logic
What are the two basic laws of probability?
What are the five rules of probability?
- Probability Rule One (For any event A, 0 ≤ P (A) ≤ 1)
- Probability Rule Two (The sum of the probabilities of all possible outcomes is 1)
- Probability Rule Three (The Complement Rule)
- Probabilities Involving Multiple Events.
- Probability Rule Four (Addition Rule for Disjoint Events)
What are some real life examples of probability?
What are some real life examples of probability? Some examples of probability include: There is a 20 percent chance of rain tomorrow. Based on how poorly the interview went, it is unlikely I will get the job. Since it is 90 degrees outside, it is impossible it will snow. After flipping this coin 10 times and having it land on heads 8 times, the probability of landing on heads is still 50 percent.
Can 0.08 be a probability?
P(Screen Positive)=0.08, i.e., the probability of screening positive overall is 8% or 0.08.
What Cannot be a probability?
A probability is always greater than or equal to 0 and less than or equal to 1. hence, only A and C above cannot represent probabilities. -0.00001 is less than 0 and 1.001 is greater than 1. Was this answer helpful?
Can Value 5 be a probability?

Can 0.5 be a probability?
A probability of 0.5 is the same as odds of 1.0. Think of it this way: The probability of flipping a coin to heads is 50%. The odds are “fifty: fifty,” which equals 1.0.
Can zero be a probability?
A probability of 0 means that the event will not happen. For example, if the chance of being involved in a road traffic accident was 0 this would mean it would never happen. You would be perfectly safe.
Can fractions be probabilities?
Probability is the number that describes the chance that a particular event will occur. Probability can be expressed in many different ways, including as a fraction.
Can a probability be negative?
The probability of the outcome of an experiment is never negative, although a quasiprobability distribution allows a negative probability, or quasiprobability for some events. These distributions may apply to unobservable events or conditional probabilities.
Can a decimal be a probability?
Probabilities can be written as fractions, decimals or percentages. You can also use a probability scale, starting at (impossible) and ending at (certain).
What numbers can be probabilities?
This means a probability number is always a number from 0 to 1. Probability can also be written as a percentage, which is a number from 0 to 100 percent. The higher the probability number or percentage of an event, the more likely is it that the event will occur.
Is 1.3 a probability?
In terms of decimals, we know from the rules of probability that, for any event 𝐸 , 0 ≤ 𝑃 ( 𝐸 ) ≤ 1 . Since 1.3 is greater than 1, 1.3 cannot represent the probability of an event occurring.
Can 0.0002 be a probability?
(c) 0.0002 lies between 0 and 1, thus 0.0002 can represent the probability of an event.
Can a probability be more than 1?
So, the value of probability always lies between 0 and 1, cannot be greater than 1. The definition of probability is composed in such a way that the value of probability lies between -1 and +1. It can not be more than +1 and less than -1.
Can a negative number be a probability?
The probability of the outcome of an experiment is never negative, although a quasiprobability distribution allows a negative probability, or quasiprobability for some events.
Can a decimal be a probability?
Probabilities can be written as fractions, decimals or percentages. You can also use a probability scale, starting at (impossible) and ending at (certain).
What are the 3 rules of probability?
General Probability RulesRule 1: The probability of an impossible event is zero; the probability of a certain event is one. ... Rule 2: For S the sample space of all possibilities, P(S) = 1. ... Rule 3: For any event A, P(Ac) = 1 - P(A). ... Rule 4 (Addition Rule): This is the probability that either one or both events occur.a. ... b.More items...
Can a square root be a probability?
Square roots of probabilities appear in several contexts, which suggests that they are somehow more fundamental than probabilities. Square roots of probabilities appear in expressions of the Fisher-Rao Metric and the Hellinger-Bhattacharyya dis- tance.
