Heart failure is due to either natural occurrences (86%) or outside factors (14%). Outside factors are related to induced substa
nces or foreign objects. Natural occurrences are caused by arterial blockage, disease, and infection. Suppose that 18 patients will visit an emergency room with heart failure. Assume that causes of heart failure between individuals are independent. Round your answers to three decimal places (e.g. 98.765).
(a) What is the probability that 3 individuals have conditions caused by outside factors?
Probability =
(b) What is the probability that 3 or more individuals have conditions caused by outside factors?
Probability =
(c) What is the mean and standard deviation of the number of individuals with conditions caused by outside factors?
I'm not exactly sure but I think it might be but if you were to do 4(x-7) that would be 15 because fifteen minutes seven equals eight and eight time four is thirty two Hope this helps!
