Examples, solutions, worksheets, videos, and lessons to help Grade 7 students learn how to approximate the probability of a chance event by collecting data on the chance process that produces it and observing its long-run relative frequency, and predict the approximate relative frequency given the probability.
For example, when rolling a number cube 600 times, predict that a 3 or 6 would be rolled roughly 200 times, but probably not exactly 200 times
Common Core: 7.SP.6
Suggested Learning Targets
- I can distinguish the difference between relative
frequency (experimental probability) and
- I can use probability to predict the number of times
a particular event will occur.
- I can find probabilities when given sample spaces
for simple events using methods such as
organized lists and table.
- I can collect data to approximate probability

Predicting with probability
Observing actual result
If you roll a number cube 240 times, how many times would you expect to get a 1 or a 4?
Theoretical and Experimental Probability
This lesson explains the difference between Theoretical and Experimental Probability.
Theoretical probability shows what should happen in an experiment.
Experimental probability shows what actually happens in an experiment.
Theoretical Probability versus Experimental Probability
Comparing theoretical and experimental probability.
Probability: Making Predictions
Use probability and proportion to make predictions based on a survey.
Making Predictions Probability
Taking the probability of an event and predicting what a larger sample would result.
Use basic probability to make a prediction.
Step 1: Set up a proportion
Step 2: Use cross multiplication or equivalent fractions to solve.
You have 25 blocks in a bag. There are 15 red, 4 blue and 6 yellow blocks. If you pill a block out of the bag and replace it 200 times, how many times would you pull out a blue block?
