A survey of people in a given region showed that \(20 \%\) were smokers. The probability of death due to lung cancer given that a person smoked was 10 times the probability of death due to lung cancer, given that a person did not smoke. If the probability of death due to lung cancer in the region is 0.006 . What is the probability of death due to lung cancer given that a person is a smoker?
- A \(1 / 140\)
- B \(1 / 70\)
- C \(3 / 140\)
- D \(1 / 10\)
Answer & Solution
Correct Answer
(C) \(3 / 140\)
Step-by-step Solution
Detailed explanation
Let \(S=\) Event that person is smoker \(\mathrm{NS}=\) Event that person is non-smoker \(D=\) Event that death is due to lung cancer. Now, probability of death due to cancer that a person is a smoker,…
