Problem. Suppose that in a survey of college students, 30% of students regularly drink coffee, 20% of students regularly drink tea, and 40% of students regularly drink coffee or tea. Consider randomly selecting one of surveyed students. (a) Define the events as follows: A = a randomly selected student regularly drinks coffee. B = a randomly selected student regularly drinks tea. From the question, you were provided three probabilities. Translate all three of them into appropriate probability notations. 1. "30% of students regularly drink coffee' PI ) = 2. "20% of students regularly drink tea" PO ) = 3. "40% of students regularly drink coffee or tea" PC ) = (b) What is the probability that the selected student regularly drinks both coffee and tea? If you are using any probability rules to solve this problem, you also, must clearly state its name. Show all your work.
