Write a Probability Distribution

Front

What is a probability distribution?

Back

A probability distribution is a mathematical function that describes the likelihood of obtaining the possible values that a random variable can take.

What is the difference between discrete and continuous data?

Back

Discrete data consists of distinct, separate values (e.g., number of students), while continuous data can take any value within a range (e.g., height, temperature).

Front

Give an example of discrete data.

Back

The number of cheeseburgers a fast-food restaurant serves each day.

Front

Give an example of continuous data.

Back

The temperature of a room.

Front

What type of data is the number of pages in a book?

Back

Discrete Data.

Front

What is the sum of probabilities in a probability distribution?

Back

The sum of all probabilities in a probability distribution must equal 1.

Front

What is a random variable?

Back

A random variable is a variable whose possible values are numerical outcomes of a random phenomenon.

Front

What is the probability of an event?

Back

The probability of an event is a measure of the likelihood that the event will occur, ranging from 0 (impossible) to 1 (certain).

Front

What is a cumulative distribution function (CDF)?

Back

A cumulative distribution function (CDF) gives the probability that a random variable is less than or equal to a certain value.

Front

What is the mean of a probability distribution?

Back

The mean of a probability distribution is the expected value, calculated as the sum of all possible values multiplied by their probabilities.
