A study has been conducted to explore the effects of smoking on lung cancer deaths.
2400 deaths were studied. 660 of these records were belonging to smokers. 160 of the
total deaths were due to lung cancer. 20 people who died to due to lung cancer were
non-smokers. Using the data above, calculate the following probabilities
P(LungCancer ∩ Smoker) =?
• P(lungCancer │Smoker) =?
• Probability the cause of death was lung cancer given that the record belongs to a non
smoker?
• P(LungCancer U Smoker) =?
