This product includes three
different probability experiments. Students will complete an experiment and will deepen their understanding of experimental and theoretical probability
through a variety of questions. Each experiment is completed on a two page worksheet. Space is provided for students to record their data. For the three resources, you will need coins, a paper clip and dice.
❶ Heads or Tails – A Probability Experiment
Students will explore experimental and theoretical probability by flipping three coins 25 times. In order to examine the theoretical probability, students are asked to make a prediction, create a counting tree and make an organized list of the outcomes. Students are asked three questions about the expected value of getting HHH, TTT or a combination of heads/tails.
On the second page, space is provided for students to record 25 outcomes from the experiment of flipping three coins. Students are asked to use percents to compare the theoretical probability to their experimental probability. Three additional questions ask students to find the expected value of flipping coins three times to obtain HHH, TTT or a combination of heads/tails.
❷ Spin to Win – A Probability Experiment
The second experiment, Spin to Win has students spinning two spinners to obtain two possible desired outcomes: rainbow/pot of gold and four leaf clover/four leaf clover. If the students spin anything else (example: rainbow/2 or clover/4), the outcome is not considered a win. The activity has students determine and compare experimental and theoretical probabilities. Students are asked to answer six questions after experiment. Students can use a paper clip to conduct a spin.
❸ Rolling Doubles – A Probability Experiment
The third experiment asks students to roll a pair of dice 24 times. They will record the sum of their roll and will circle any sums that were a result of doubles being rolled. Questions ask student to determine the experimental and theoretical probabilities of various events when rolling the dice, how many total outcomes exist, and if this would be a good game to use to earn money at a potential fun fair.
Answer keys are included for all of the experiments.
