## What is an example of a simple event

A simple event is an event where all possible outcomes are equally likely to occur.

…

For example, when you toss a coin, there are two possible outcomes – heads or tails, and the probability of heads or tails is equal..

## What is an example of a certain event

Certain Event. A certain event is an event that is sure to happen. E is a certain event if and only if P(E) = 1. In flipping a coin once, a certain event would be getting a head or a tail.

## What is the probability of A or B

If the events A and B are not mutually exclusive, the probability is: (A or B) = p(A) + p(B) – p(A and B).

## What is the probability of the event that a number chosen from 1 to 100 is a prime number

The probability for the set of numbers from 1 to 100 is . 25, because 25/100 numbers in that set are primes (which are 2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37, 41, 43, 47, 53, 59, 61, 67, 71, 73, 79, 83, 89, 97).

## What is the meaning of a zero probability for an event

An event with a probability of zero [P(E) = 0] will never occur (an impossible event). An event with a probability of one [P(E) = 1] means the event must occur (a certain event).

## What is the probability of an impossible event

Answer: The probability of an impossible event is 0. Because it cannot occur in any situation.

## What is impossible event give example

A probability of 0 the event is impossible, or can never happen. E is an impossible event if and only if P(E) = 0. Examples : 1) In flipping a coin once, an impossible event would be getting BOTH a head AND a tail.

## Can the probability of an event be greater than 1

The probability of an event will not be more than 1. This is because 1 is certain that something will happen.

## Does probability 0 mean impossible

Events that are impossible have zero probability, but the converse is not necessarily true. Clearly an empty set has zero probability. But, a zero probability event does not mean an impossible event. … Every point has zero probability but every point can be a possible outcome.

## What does probability look like

Probability is the likelihood or chance of an event occurring. For example, the probability of flipping a coin and it being heads is ½, because there is 1 way of getting a head and the total number of possible outcomes is 2 (a head or tail).

## What is an event with a probability of 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. A probability of 1 means that the event will happen.

## What is the probability of an impossible event Mcq

An event that cannot occur is called an impossible event. The probability of an impossible event is 0.

## What is the formula of probability

P(A) is the probability of an event “A” n(A) is the number of favourable outcomes. n(S) is the total number of events in the sample space….Basic Probability Formulas.All Probability Formulas List in MathsConditional ProbabilityP(A | B) = P(A∩B) / P(B)Bayes FormulaP(A | B) = P(B | A) ⋅ P(A) / P(B)5 more rows

## Is 0 an impossible event

Impossible Event. An impossible event is an event that cannot happen. E is an impossible event if and only if P(E) = 0. In flipping a coin once, an impossible event would be getting BOTH a head AND a tail.

## Which is the probability of an event

In an experiment, the probability of an event is the likelihood of that event occuring. Probability is a value between (and including) zero and one. If P(E) represents the probability of an event E, then: P(E) = 0 if and only if E is an impossible event.

## What kind of values Cannot be probabilities

The student does not understand that a probability must be between zero and one. The student understands that a negative number cannot represent a probability but states that: All positive or all whole numbers can be probabilities. Numbers greater than one can be probabilities while numbers less than one cannot.
