In this activity, students will use a simulation to find the experimental probability of independent events, tossing two coins. They will find the sample space and then compare the experimental and theoretical probabilities.
To start the activity, students are to predict what they think will be the probabilities of the outcomes of tossing a coin twice.
Then, to quickly determine the sums of 0, 1, and 2 tails, students should use the Quick Graph feature. Students then calculate the experimental probabilities of tossing 0, 1, and 2 tails.
