# Probability & Frequency

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 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
