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) (6 points) 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' P( ) =

2. "20% of students regularly drink tea" P( ) =

3. "40% of students regularly drink coffee or tea" P( ) =
