Choose an American adult at random. Define two events:    A = the person has a cholesterol level of 240 milligrams per deciliter of blood (mg/dl) or above (high cholesterol)  B = the person has a cholesterol level of 200 to <240 mg/dl (borderline high cholesterol)    According to the American Heart Association, P(A) = 0.16 and P(B) = 0.29.  Explain why events A and B are mutually exclusive.  Say in plain language what the event “A or B” is.  Find P(A or B).  Let C be the event that the person chosen has normal cholesterol (below 200 mg/dl). Find P(C).
