This is my current code:

Open the Terminal window and make sure that 'Clear screen at method call' is unticked in the Options menu. Starting with your best guess, use the object you created to call the runSimulation method using different numbers of attendees until you discover the minimum number of attendees for there to be a 50% chance or more of having at least one pair of matching birthdays. Take a screenshot of the Terminal window showing your tests and their results and paste it into your Solution Document. Hint: The number you are looking for must be between 2 and 367 (if there are fewer than 2 people, there cannot be a matching birthday and if there are 367 people there is guaranteed to be a match). So, start with your best guess and then raise it if it gives a probability less than 50% and lower it if it gives a probability of more than 50%, and continue until you narrow it down to a single number of attendees
