## What probability is not possible?

The probability of an impossible event is **0**.

## Which is not a method of assigning probability?

**Personal approach** is NOT an approach for assigning the probability of the event. Relative frequency can be calculated by taking the count of an individual kind of outcome and divide by the total counts for all kinds of outcomes.

## What Cannot be the probability of an event occurring?

Thus the probability of an event that cannot happen is **0**.

## What Makes a probability unlikely?

**An unlikely event would have a probability between 0 and ½**. A likely event would have a probability between ½ and 1.

## Which of the following is not possible probability distribution?

**p(x) = -0.5** is not possible since the probability cannot be negative.

## Which of the following is possible probability?

Answer. Because the possible probability of an event is always comes **between 0 to 1**.

## Which of the following Cannot be the value of probability of the random variable?

Answer and Explanation: A probability ranges from 0 to 1 . That is, **any negative number** cannot be treated as a probability.

## Which of the following is not a continuous probability distribution?

Therefore it is the **discrete probability distribution**. Hence the correct option is option C. That is poison.

## Which of the following can be the probability of an event?

Explanation: An event’s probability **cannot be less than one, nor can it be greater than one**.

## At what point is something considered mathematically impossible?

A statistical impossibility is **a probability that is so low as to not be worthy of mentioning**. Sometimes it is quoted as 10−50 although the cutoff is inherently arbitrary. Although not truly impossible the probability is low enough so as to not bear mention in a rational, reasonable argument.

## What is the probability of obtaining 45 or fewer heads in 100 tosses of a coin?

1. What is the probability of obtaining 45 or fewer heads in 100 tosses of a coin? binomcdf(100,. 5,45) = **0.184** *try on calc!

## What is the probability of getting a head when a coin is tossed once?

The probability of getting heads or tails is **1/2**.

Thus, the probability of getting a head or tail is 1/2.

## Can the value be a probability?

**Probability is a value that specifies whether or not an event is likely to happen**. The value generally lies between zero to one. If an event comes out to be zero, then that event would be considered successful. If an event comes out to be one, then that event would be considered a failure.

## Which of the following Cannot be the value of probability of the random variable?

Answer and Explanation: A probability ranges from 0 to 1 . That is, **any negative number** cannot be treated as a probability.

## What if the probability of an event is 0?

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 the probability of an event be greater than 1?

Probability of occurrence of an event **can never be greater than 1**.

## Can a probability be less than 0?

Probabilities range from 0 to 1

Probability is a measure of the likeliness or chance of possibilities in a situation. It is not possible to have a length or area or weight or height less than zero. In the same way, **probability cannot be below 0**. You can’t have less than zero chance of something happening.

## Is there any possibility that a probability will exceed 1 Why or why not?

**Probability of an event cannot exceed 1**. probability of any thing will lie between 0 to 1.

## Is it possible to have a probability of 1?

**An event that is certain to happen has a probability of 1**. An event that cannot possibly happen has a probability of zero. If there is a chance that an event will happen, then its probability is between zero and 1.

## What must be true for a number to be a probability?

A probability must be **between zero and one**. (c) Explain why 120% cannot be the probability of some event. A probability must be between zero and one. (d) Can the number 0.56 be the probability of an event?

## What are the 3 rules of probability?

There are three main rules associated with basic probability: **the addition rule, the multiplication rule, and the complement rule**.

## Can you conclude that events A and B are not independent if they are mutually exclusive?

can you conclude that events A and B are not independent if they are mutually exclusive? Explain. **Yes.** **Because P(A|B) ≠ P(A), the events A and B are not independent.**
