Independent and Mutually Exclusive Events · Try It 7
A student goes to the library. Let events B = the student checks out a book and D = the student checks out a DVD. Suppose that P(B) = 0.40, P(D) = 0.30 and P(B AND D) = 0.20.
(a) Find P(B|D).
(b) Find P(D|B).
(c) Are B and D independent?
(d) Are B and D mutually exclusive?
Its source prints no answer for this problem, so there's nothing to check against.
