7th grade probability lessons

Quick answer

This 7th grade (ages 12–13) playlist covers probability from the 0-to-1 scale through theoretical and experimental probability, simulations, sample spaces, tree diagrams and compound events. It opens with Math Antics' "Basic Probability", then Math with Mr. J and Khan Academy. Loop one worked example with A–B and repeat it until it is clear.

What should a student be able to do after this unit?

Describe likelihood on a scale from 0 to 1, find the probability of simple events, compare theoretical and experimental results, make predictions, list sample spaces with tables and tree diagrams, and find the probability of compound events such as two coin flips.

How does RepeatWatch help with tree diagrams?

Tree diagrams are drawn step by step. Slow the video to 0.75× and loop the part where the branches are drawn, so a student can copy each branch. Save each example on keys 1–9 and stop after a set number of loops.

Frequently asked questions

What is the difference between theoretical and experimental probability?

Theoretical probability is what should happen, based on equally likely outcomes. Experimental probability is what actually happened in trials, such as 100 coin flips. Math with Mr. J's "Theoretical vs. Experimental Probability" compares them.

Is probability a 7th grade topic everywhere?

Grade levels vary by country and school. In the US, probability models and compound events are usually covered in 7th grade (ages 12–13). Other countries may introduce them earlier or later.
