Contingency Table

A contingency table can be defined as the visual representation of the relationship between two or more categorical variables that can be evaluated and registered. It is a categorical version of the scatterplot, which is used to investigate the linear relationship between two variables. A contingency table is indeed a type of frequency distribution table that displays two variables at the same time.

Binomial Distribution

Binomial is an algebraic expression of the sum or the difference of two terms. Before knowing about binomial distribution, we must know about the binomial theorem.

Question

The image is from an online educational platform, specifically a lesson on discrete random variables. Here, students are asked to construct a discrete probability distribution for a random variable representing the "number of tails in 3 tosses of a coin." The probabilities should be expressed as simplified fractions.

### Question:
- **Objective:** Construct the discrete probability distribution.
- **Random Variable:** Number of tails in 3 coin tosses.

### Answer Section:
A table is presented with the following columns:
- **x (Number of Tails):** 0, 1, 2, 3
- **P(X = x):** Students are expected to fill in the probabilities for each outcome.

There are tools available to help students input their answers:
- **Tables:** A button presumably offering a way to organize data or access tables.
- **Keypad** and **Keyboard Shortcuts:** Assist with data entry and ease of input.

The page includes a progress indicator showing a score of 15/22 correct answers given so far.

At the bottom, there is a "Submit Answer" button for students to finalize their responses.

This exercise is part of Lesson 6.1-6.3 on discrete random variables from Hawkes Learning.
