A two-digit number is selected by randomly choosing two digits from 1 to 4 using randint(1, 4) on the calculator until two different numbers are chosen. For example, if the output was 3 and then I, the number would be 31, but if the output was 3 followed by a 3, a new number would have to be selected for the second a. Find a probability model for this chance process. b. Find the probability that the number does not start with a 1. c. What is the probability that the number selected is divisible by 3
