                        Smoking increases the risk of lung problems. A study revealed that 170 in 1000 males who smoke develop lung complications, while 120 out of 1000 females who smoke develop lung related problems. In a colony, 50 people were found to be smokers of which 30 are males. A person is selected at random from these 50 people and tested for lung related problems. Based on the given information answer the following questions: 

                        (i) What is the probability that selected person is a female? 
                        (ii) If a male person is selected, what is the probability that he will not be suffering from lung problems? 
                        (iii)(a) A person selected at random is detected with lung complications. Find the probability that selected person is a female.
