Suppose you roll a fair 15 sided die. The numbers 1-15 appear once on different sides. (Imagine a regular die with 12 sides instead of 6.) Answers may be left in formula form.
(a) What is the probability of rolling a 7?
(b) What is the probability of rolling an odd number and a number greater than 8?
(c) What is the probability of rolling an even number or a number greater than 9?
(d) Suppose you roll the die, record the number you see, and then roll it again. What is the probability that the sum of the die is 11?
(e) Suppose you roll the die, record the number you see, and then roll it again. What is the probability of rolling a 3 and then rolling a 3 again?
