Experimental Probability and Simple Trials

Experimental Probability and Simple Trials

What students learn

Students learn that experimental probability comes from doing a real test, counting what happened, and comparing the results. Begin with Experimental Probability: Start a Small Trial so students can see the experiment begin.

Why it matters

A single trial can be surprising, but a set of trials gives a clearer picture. Experimental Probability: Record Results Carefully shows how the results matter more than a guess.

Learn the idea

Experimental probability is based on actual outcomes, not just what seems likely before the experiment starts. After enough trials, the result often gets closer to the expected chance. Experimental Probability: More Trials Change Results helps students see why repeated trials matter.

Try it

Flip a coin 10 times or roll a die 12 times. Record the results, count the outcomes, and compare the experimental probability to the chance you expected before the experiment.

Parent guide

Use a simple setup and keep the counts visible. Ask the child to say what they predicted, what actually happened, and whether the experiment matched the prediction. If needed, repeat the trial and compare the new result.
