An interactive provides a model to visually represent the formula for the probability of an outcome. Given 10 numbered color cubes, pupils arrange them on the top and bottom shelf to represent the probability fraction. The learners use...

The car is behind door one — no wait, it is behind door three. An interactive allows learners to visualize the Monty Hall problem. Pupils work through the probabilities of choosing the car with their first pick. Next, they determine...

An interactive uses a candy store to involve the pupils in conditional probabilities. Learners determine probabilities as customers purchase different types of candies and the stock decreases.

You first! An interactive sets up a game between two friends who hope they don't find a lemon hidden under a tray. Pupils determine whether there is an advantage of going first. Individuals find the probabilities of each friend finding...

Challenge individuals to compete as many tasks as possible. Lower-level tasks have pupils apply costs and rates to solve problems. Upper-level tasks add algebraic reasoning and conditional probability to the tasks.

What are your chances of being audited by the IRS? An engaging problem scenario asks pupils to examine the likelihood of being audited compared to factors such as receiving a refund or claiming a home office. The final product of the...

Quickly assess basic understandings of statistics and probability. The resource contains five quick tasks from the probability and statistics domain. The questions range from finding simple conditional probabilities to measures of center...

Investigate the effect of false positives on probability calculation with an activity that asks scholars to collect simulated data generated by a calculator. To finish, participants analyze the probability of certain outcomes which lead...

Will it rain during the weekend? Pupils become meteorologists for a day as they use the assessment to determine the chance of rain for Saturday and Sunday. Class members interpret the weather statements as they pertain to probabilities...

Class members determine the chance of surviving two years by explaining the concept of probability expressed in a medical terms. Would-be doctors continue to explain a conditional probability statement as it relates to the total population.

Class members demonstrate a proficiency with conditional probabilities through this task. Individuals calculate probabilities using multiplication and addition. They also distinguish between repetition and non-repetition while...

You can't win if you don't play! Find out how to increase your chances of winning the lottery. Scholars analyze a state lottery system for the probability of winning. They also consider different combinations of numbers and how they...

Test probability concepts with an activity that asks pupils to first complete a task investigating false positive in medical testing and then to evaluate sample responses to the same task.

Middle schoolers must determine probabilities for a memory game in which winning requires matching two of the same cards. They then must determine what happens when more cards are added to the pile.

The test may say you have cancer, but sometimes the test is wrong. The provided task asks learners to analyze cancer statistics for a fictitious town. Given the rate of false positives, they interpret the meaning of this value in the...

Learning about probability and enjoying the lesson don't have to be disjoint events. A helpful video guides pupils through a few examples of probability with dice and cards to show how the formula calculates the result. 

Let's compare the difference between getting lung cancer and then the higher chance of getting lung cancer when you already are a smoker. The video discusses the idea of conditional probability and how a previous event will change the...

Branch out with a tree diagram. A presentation on complex probability explains the process of creating a tree diagram to represent the possible outcomes in a scenario. It then uses the diagram to calculate the probabilities of each of...

The key to understanding conditional probability is understanding the context of the problem presented. The video presents two questions with a subtle difference between them, then teaches scholars to decipher the difference and...

Under which condition should you calculate a conditional probability? An educational video explains in detail the notation and calculations involved when finding a conditional probability. Using Venn diagrams to organize the information,...

Candy is always an effective motivator! A fun math activity uses M&M's and Skittles to explore two-way frequency tables and conditional probability. The candy can serve a dual purpose as manipulatives and experimental data.

Bring the concept of conditional probability alive by allowing your classes to explore different probability scenarios. Many tasks have multiple solutions that encourage students to continue exploring their problems even after a solution...

Making connections between multiple methods of solving problems is an important part of understanding conditional probability. The lesson shows solutions to problems using Venn diagrams, tree diagrams, formulas, and two-way tables....

Conditional probability can be a confusing concept. A straightforward lesson provides reasonable examples of conditional probability, and models the most effective ways to reinforce the more complex parts of the lesson.
