Grade 6 · Math · Lesson 28

Probability Experiments

Probability is a number that tells you how likely something is to happen. Flip a fair coin and you expect heads about half the time; roll a fair die and you expect a 4 about one time in six. When you actually run the trials and count what you saw, the fraction (favourable outcomes) / (total trials) is the experimental probability — the answer the experiment gave you.

What this lesson teaches

1Compute the experimental probability of an event as favourable outcomes divided by total trials
2Express probabilities as fractions, decimals, or percents between 0 and 1
3Place probability values on a 0-to-1 scale to compare how likely events are
4Interpret words like impossible, unlikely, even chance, likely, and certain in terms of numerical probability
