asked in category: General Last Updated: 2nd April, 2020# Which of following Cannot be probability of an event?

**probability of an event cannot**be - 1.5 because

**Probability of an event can never**be negative. The

**probability**of happening of an

**event**always lies between 0 to 1 (0 and 1 inclusive) i.e 0 ≤ P(E) ≤ 1 . Also in percentage, it lies between 0 % to 100 %(0 and 100 inclusive) .

Then, which of the following Cannot be a probability?

1 Expert Answer **Probabilities** must be between 0 and 1 or 0% and 100% and **cannot** be negative. Therefore, 100% is valid for a **probability**, . 8 is valid for a **probability**, 75% is valid for a **probability**, while -. 2 is not valid for a **probability**.

Furthermore, can the probability of an event be negative? **Negative 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. These distributions may apply to unobservable events or conditional **probabilities**.

Also to know is, what is the probability of an event that is impossible?

Properties of **Probability**. In words, this means that the **probability of an event** must be a number between `0` and `1` (inclusive). In words: The **probability** of an **impossible event** is `0`. In words: The **probability** of an absolutely certain **event** is `1`.

What is a valid probability?

A **probability** function is a function which assigns **probabilities** to the values of a random variable. All the **probabilities** must be between 0 and 1 inclusive. The sum of the **probabilities** of the outcomes must be 1.
