Simulation: Birthday Problem Suppose there are 30 people at a party. Do you think any two share the same birthday Let's use the random-number table to simulate the birthdays of the 30 people at the party. Ignoring leap year, let's assume that the year has 365 days. Number the days, with 1 representing January 1, 2 representing January 2, and so forth, with 365 representing December 31. Draw a random sample of 30 days (with replacement). These days represent the birthdays of the people at the party. Were any two of the birthdays the same Compare your results with those obtained by other students in the class. Would you expect the results to be the same or different
