Khan Academy: Intro to Theoretical Probability

If you keep rolling a die, you'll roll a five exactly one-sixth of the time—right? A probability lesson prompts young mathematicians to roll a die 100 times and use the data to calculate empirical probabilities. They then compare...

Flip a coin to determine whether the probability of heads is one-half. Pupils use simulated data to find the experimental probability of flipping a coin. Participants compare the long run relative frequency with the known theoretical...

Cultivate the tree of knowledge using diagrams with two stages. Pupils create small tree diagrams to determine the sample space in compound probability problems. The lesson uses only two decision points to introduce tree diagrams. 

Calculate theoretical probabilities and compare them to experimental probabilities. Pupils build on their knowledge of experimental probabilities to determine theoretical probabilities. Participants work several problems with the...

Your learners will be surprised by the thought-provoking, counterintuitive puzzle presented in this short video that models a fun, fictional situation in which a game is played with two number cubes to decide which of two people wins a...

Explains what cube roots are and how to find them, including the cube root of a negative number. [8:00]

By watching this video lesson, students will learn the meaning of cube roots and how to find the cube root of a negative number. [8:00]

Video tutorial provides an introduction to square roots. Learn about the square root symbol (the principal root), what it means to find a square root, and how to solve simple square root equations. [5:23]

You can calculate the theoretical probability of an event without actually testing it. Mathematicians who are new to probability or those who simply need to review will benefit from watching this video of a teacher solving two problems...

Practice making predictions with probability with these problems.
