Run this with a digital tool

This standard asks students to run repeated chance experiments and simulations with digital tools. Use ChalkBee's interactive probability simulator to run coin flips, die rolls, spinner spins or counter draws, from 10 up to 10,000 trials, and watch the relative frequency converge on the theoretical probability. It also has a conditional-probability mode for dependent events.

Teaching guide

What students learn

Run repeated chance experiments and simulations with more trials using digital tools, comparing observations with expected results.

How to teach it

Order events from impossible to certain in everyday language, then quantify simple chances as fractions of the equally-likely outcomes.

Worked example
A bag has 8 balls. 2 are red. What is the probability of picking a red one? Write it as a fraction.
Answer: 2/8
Why: favourable 2 out of 8 total = 2/8

Generated and checked in code, so it is correct.

Watch out for

Assuming a rare-but-possible event is impossible, and thinking past results change the next independent outcome.
