Two thousand adults were asked if they are financially better off than their parents and how much school they have finished. The results are in the table. Are the events W = "worse off" and M = "more than high school" independent? Why or why not?

A) Yes; because P (W & M) = P (W) + P (M).

B) No; because P (W & M) ≠ P (W) + P (M).

C) Yes; because P (W & M) = P (W) · P (M).

D) No; because P (W & M) ≠ P (W) · P (M).

I think it's D but I want to make sure, you know?
