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) =?

Refrigerant 134a enters an insulated compressor operating at steady state as saturated vapor at -26°c with a volumetric flow rate of 0.18 m3/s. refrigerant exits at 9 bar, 70°c. changes in kinetic and potential energy from inlet to exit can be ignored. determine the volumetric flow rate at the exit, in m3/s, and the compressor power, in kw.
