            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. 
            OR 
            (iii)(b) A person selected at random is not having lung problems. Find the probability that the person is a male.

                    A line passing through the points \(A(1,2,3)\) and \(B(6,8,11)\) intersects the line \[ \vec r = 4\hat i + \hat j + \lambda(6\hat i + 2\hat j + \hat k) \] Find the coordinates of the point of intersection. Hence write the equation of a line passing through the point of intersection and perpendicular to both the lines.
