Probability of simple events

7th Grade Math: The Test that Shall not be named Day 7

7.SP.5 Understand that the probability of a chance event is a number between 0 and 1 that expresses the likelihood of the event

occurring.

7.SP.6 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

7.SP.8 Use lists and tree diagrams for events. Make predictions

Theoretical vs Experimental Probability

Theoretical Probability:

is calculating the probability of what should happen. (What should happen)


Experimental Probability:

is calculating the probability based on the results of an experiment. (What does happen)
