Hi Everyone!

I'm so happy to have found this forum. I am the absolute worst at math, and I'm almost positive I'm doing this problem wrong. I would be extremely helpful for any help!

- The following table shows the number of patients with different types of disorders / disease associated with patients at General Hospital within the last year. Assume each patient has only one disorder

Types of Disorders / DiseaseNumber of Patients with Disorder / DiseaseLiver Disease 346 Lung Cancer 147 Heart Disease 232 Diabetes 187 Alzheimer’s 93

- Find the probability that a random person selected has liver disease
- Find the probability that a random person selected has lung cancer or liver disease or heart disease
- Find the probability that a random person selected has liver disease and lung cancer

d. What type of probability calculation approach is being exercised in this example (classical, relative frequency or subjective)?

My answers:

a. 346/1005 = .34

b. (147+346+232)/1005 = .72

c. Not really sure what my professor is asking here. The question says to assume each person has only one disorder.

d. Classical

Thanks again for your time everybody!
