standard_description: 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.
problem_activity: Task
Decide if the equations are true or false. Explain your answer.
4 x 5 = 20
34 = 7 x 5
3 x 6 = 9 x 2
5 x 8 = 10 x 4
6 x 9 = 5 x 10
2 x (3 x 4) = 8 x 3
8 x 6 = 7 x 6 + 6
4 x (10 + 2) = 40 + 2
