In a given training center, the total number of students is (100) students. (70) students are taking training course 1, and (50) students are taking training course 2. (30) students are taking both course 1 and course 2. A. A student is chosen randomly; what is the probability that the student is taking none of these two courses? B. A student is chosen randomly; what is the probability that the student is taking both of these two courses? C. A student is chosen randomly; what is the probability that the student is taking any of these two courses? D. If 5 students are chosen randomly; what is the probability that at least 2 students are taking both courses? E. If 5 students are chosen randomly; what is the probability that at most 2 students are taking none of both courses? F. If 5 students are chosen randomly; what is the probability that at most 3 students are taking any of these two courses? G. Define two events as follows: A: The student is taking course 1. B: The student is taking course 2. Are events (A & B) independent or not? Justify your answer. In a given training center, the total number of students is (100) students.
