Question 180043: Suppose that 53% of all adults in a certain community are obese and that 46% suffer from diabetes. If 26% of the adults in this community are both obese and suffering from diabetes, what is the probability that a randomly chosen adult in this community is obese or suffers from diabetes (or both)?

Suppose that 53% of all adults in a certain community are obese and that 46% suffer from diabetes. If 26% of the adults in this community are both obese and suffering from diabetes, what is the probability that a randomly chosen adult in this community is obese or suffers from diabetes (or both)?
---------------------
General Formula:
P(A or B) = P(A) + P(B) - P(A and B)
--------------------------------------
Your Problem:
P(obese or diabetes) = P(obese)+P(diabetes) - P(obese and diabetes)
= 53% + 40% - 26%
= (93-26)%
= 67/100
