4. The probability that a randomly chosen male has pneumonia problem is 0.40. Smoking has substantial adverse effects on the immune system, both locally and throughout the body. Evidence from several studies confirms that smoking is significantly associated with the development of bacterial and viral pneumonia. 80% of males who have pneumonia problem are smokers. Whilst 30% of males that do not have pneumonia problem are smokers. i. What is the probability that a male is chosen do not have pneumonia problem? ii. Determine the probability that a selected male has a pneumonia problem given that he is a smoker.

A thermometer is removed from a room where the temperature is 70° F and is taken outside, where the air temperature is 10° F. After one-half minute the thermometer reads 57° F. What is the reading of the thermometer at t = 1 min? Assume that the rate of change of temperature in time is proportional to the difference between the thermometer's temperature and the air temperature. Type your answer in °F in the space provided below. Round your answer to two decimal places.
