Two Basic Rules of Probability · Exercise 31
A college finds that 10% of students have taken a distance learning class and that 40% of students are part time students. Of the part time students, 20% have taken a distance learning class. Let D = event that a student takes a distance learning class and E = event that a student is a part time student
(a) Find P(D AND E).
(b) Find P(E|D).
(c) Find P(D OR E).
(d) Using an appropriate test, show whether D and E are independent.
(e) Using an appropriate test, show whether D and E are mutually exclusive.
