How do you know if something is a discrete probability distribution?

A discrete probability distribution lists each possible value that a random variable can take, along with its probability . It has the following properties: The probability of each value of the discrete random variable is between 0 and 1, so 0 ≤ P(x) ≤ 1. The sum of all the probabilities is 1, so ∑ P(x) = 1.

Also question is, what makes something 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.

One may also ask, what is a probability distribution for a discrete random variable What does it look like? The probability distribution of a discrete random variable x lists the values and their probabilities , where value x1 has probability p1 , value x2 has probability x2 , and so on. Every probability pi is a number between 0 and 1, and the sum of all the probabilities is equal to 1.

Keeping this in consideration, what is an example of a discrete probability distribution?

The number of ice cream servings that James should put in his cart is an example of a discrete random variable because there are only certain values that are possible (120, 130, 140, etc.), so this represents a discrete probability distribution , since this gives the probability of getting any particular value of the

What are the characteristics of a continuous probability distribution?

All probability density functions satisfy the following conditions: The random variable Y is a function of X; that is, y = f(x). The value of y is greater than or equal to zero for all values of x. The total area under the curve of the function is equal to one.
