Question 15 Suppose that % of all adults in a certain community are obese and that % suffer from diabetes. If % of the adults in this community are obese or suffer from diabetes (or both), what is the probability that a randomly chosen adult in this community is both obese and suffering from diabetes

Answer 1

The actual question is asking whether it’s an experiment or an observational study? My answer was that it’s an EXPERIMENT

Answer 2

(a%+b%)/100%

There's the formula, but you need percent values if you want the problem spot on.

Have a great day!
