Simulations with the Research Randomizer Page 4 of 6

Consider the following question:

What is the probability that in a group of 7 people chosen at random at least 2 will have a birthday in the same month?

• Design a simulation that, using the Research Randomizer, will help you estimate the probability. Describe your simulation below, making sure that your entire description appears in the box.

Carry out your simulation (the number of trials should be sufficiently large), and based on your results, answer the following questions.

• What is the probability that at least two have a birthday in the same month?

• What is the probability that at least three have a birthday in the same month?

When you are satisfied with your results, print this page and continue with the next.
