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

**Simple Event Probability (7.SP.6)**

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.**Probability Predictions**

Use basic probability to make a prediction.

Step 1: Set up a proportion

Step 2: Use cross multiplication or equivalent fractions to solve.

Example:

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?

Common Core: 7.SP.6

- I can distinguish the difference between relative frequency (experimental probability) and probability (theoretical).
- 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
