What is P (A|M), and are the events "the student is male" and "the student has blood type A" independent events?

A.; they are independent because P (A ∩ M) ≠ P (M) ⋅ P (A)

B.; they are dependent because P (A ∩ M) ≠ P (M) ⋅ P (A)

C.; they are independent because P (A ∩ M) = P (M) ⋅ P (A)

D.; they are dependent because P (A ∩ M) = P (M) ⋅ P (A)
