Hey NoviceStats.
Hint: If one person can only have one disease then the probability of having two should be 0.
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 / Disease Number of Patients with Disorder / Disease Liver 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!
