# Activities to Teach Students to Graph a Discrete Probability Distribution

As students learn about probability in their math classes, it is important for them to understand the concept of discrete probability distribution and how to graph it. Discrete probability distribution deals with the probabilities of a finite number of outcomes, as opposed to continuous probability distribution, which covers the probabilities of infinite outcomes. Graphing a discrete probability distribution helps students visually represent the probability of different outcomes, making it easier to comprehend. Here are some activities to teach students how to graph a discrete probability distribution:

1. Flip a Coin:

Begin the activity by flipping a coin and asking students to predict the probability of it landing on heads or tails. After flipping the coin several times, record the number of heads and tails on a chart, graphing the outcomes. This will help students to understand the probability distribution for each possible outcome in more detail.

2. Dice Game:

Use a pair of dice to play a game with your students. Rolling a pair of dice will result in 11 possible outcomes, ranging from rolling a two to rolling a 12. Ask your students to predict the probability of each outcome. Record the number of times each outcome occurs, creating a frequency chart. From this, students can create a graph that depicts the probability distribution of rolling two dice.

3. Classroom Survey:

Ask students to survey their classmates, asking a question that has a few different answers. For example, asking students what their favorite subject is. After tallying all of the responses, create a chart of the frequency of each answer. Students can then graph the results, visually representing the probability distribution of the answers.

4. Sampling Without Replacement:

This activity is similar to the dice game, but instead of using dice, students will be drawing colored balls from a bowl without putting them back. Begin with a bowl of six red balls and four blue balls. Without looking, ask a student to draw two balls from the bowl and record the color of each ball. After repeated trials, tally up the results and create a frequency chart. Use the frequency chart to create a graph, showing the probability distribution of the color of balls drawn.

By using interactive activities such as these, students can better grasp the concept of discrete probability distribution and how to graph it. These activities make it fun for students to learn math while increasing their understanding of probability. By implementing these activities in the classroom, teachers can build better-rounded learners who can easily communicate and understand probability distribution.
