Answer to Question 1

B

Answer to Question 2

Answers may vary. Begin by representing birthdays by integers from 1 to 365. Then use a calculator or computer
program to generate 75 random integers. Count as a success if at least five of them are the same. (The numbers can be
sorted so that this is relatively easy to determine.) Repeat for 100 trials. The estimated probability is the number of
successes divided by 100. Estimated probability is about 0.00.
