Extracted text: Heart failures are due to either natural occurrences (87%) or outside factors (13%). Outside factors are related to induced substances (73%) or foreign objects (27%). Natural occurrences are caused by arterial blockage (56%), disease (27%), and infection (e.g., staph infection) (17%). a. Determine the probability that a failure is due to induced substance. Ans = Blank 1 b. Determine the probability that a failure is either due to disease, infection, or foreign objects. Ans = Blank 2
