Step 1: Roll a die, spin a spinner, pull marbles out of bag. It is your choice.

Step 2: Create a probability question. For example, I am going to roll a die. My question is, “What is the probability of rolling a number less than 3?”

Step 3: Find the theoretical probability.

Step 4: Conduct an experiment to test your probability. You must do at least 25 trials. Bonus if you do 50 trials.

Step 5: Tell me how your relative frequency compares to the theoretical probability.
