Consider a large statistics class that has 193 students enrolled. As an ice breaker activity, the professor asks each student if they have been to Coeur d'Alene or Wendell in Idaho. After counting, the professor finds out that 62 of them have visited Coeur d'Alene, 121 of them have visited Wendell, and 34 of them have visited both Coeur d'Alene and Wendell. Define two events as follows: A = the randomly selected student has visited Coeur d'Alene. B = the randomly selected student has visited Wendell Using the information available in this problem, answer the following questions by completing the probability statement for each given situation and finding the corresponding probability. Note that A', AS, and A all denote the complement of the event A. (a) What is the probability that a randomly selected student has visited at least one of Coeur d'Alene and Wendell? If necessary, round your probability to four decimal places. P(-Select-Select- -Select- (b) What is the probability that a randomly selected student has not visited Coeur d'Alene, but has visited Wendell? If necessary, round your probability to four decimal places. P-Select --Select --Select- (c) If we learned that a student has visited Wendell, what is the probability that the student has not visited Coeur d'Alene? If necessary, round your probability to four decimal places. P(--Select- Select Select
