## What are the two requirements for a discrete probability?

In the development of the probability function for a discrete random variable, two conditions must be satisfied: (1) f(x) must be nonnegative for each value of the random variable, and (2) the sum of the probabilities for each value of the random variable must equal one.

## What are the two requirements for a discrete probability distribution quizlet?

What are the two requirements for a discrete probabilitydistribution? Each probability must be between 0 and​ 1, inclusive, and the sum of the probabilities must equal 1.

## What are the two key properties of a discrete probability distribution?

A discrete probability distribution function has two characteristics: Each probability is between zero and one, inclusive. The sum of the probabilities is one.

## What are the requirements for a distribution to be a probability distribution?

Three Requirements for probability distribution:

• The random variable is associated with numerical.
• The sum of the probabilities has to be equal to 1, discounting any round off error.
• Each individual probability must be a number between 0 and 1, inclusive. THIS SET IS OFTEN IN FOLDERS WITH

## What is discrete probability distribution example?

If you roll a six, you win a prize. Game 2: Guess the weight of the man. If you guess within 10 pounds, you win a prize. One of these games is a discrete probability distribution and one is a continuous probability distribution.

## How do you know if a distribution is discrete?

A random variable is discrete if it has a finite number of possible outcomes, or a countable number (i.e. the integers are infinite, but are able to be counted). For example, the number of heads you get when flip a coin 100 times is discrete, since it can only be a whole number between 0 and 100.

## Is the probability distribution a discrete distribution?

If a random variable is a discrete variable, its probability distribution is called a discrete probability distribution. The random variable X can only take on the values 0, 1, or 2, so it is a discrete random variable.

## Which of the following is a valid discrete probability distribution?

A valid probability distribution for a discrete random variable is the one whose sum of probabilities is 1.

## Is the following table a valid discrete probability distribution?

Yes, since all the probabilities are between 0 and 1 and the probabilities add up to one.

## What is a discrete probability distribution function?

A discrete probability distribution is applicable to the scenarios where the set of possible outcomes is discrete (e.g. a coin toss, a roll of a dice), and the probabilities are here encoded by a discrete list of the probabilities of the outcomes, known as the probability mass function.

## What is a discrete probability distribution?

A discrete distribution describes the probability of occurrence of each value of a discrete random variable. A discrete random variable is a random variable that has countable values, such as a list of non-negative integers. Thus, a discrete probability distribution is often presented in tabular form.

## Which of the following is an example of a continuous random variable?

A continuous random variable can take any value within an interval, and for example, the length of a rod measured in meters or, temperature measured in Celsius, are both continuous random variables..

## What are the 4 requirements needed to be a binomial distribution?

1: The number of observations n is fixed. 2: Each observation is independent. 3: Each observation represents one of two outcomes (“success” or “failure”). 4: The probability of “success” p is the same for each outcome.
