A drinks machine dispenses lemonade into cups. It is electronically controlled to cut off the flow of lemonade randomly between 180 ml and 200 ml. The random variable X is the volume of lemonade dispensed into a cup (a) Specify the probability density function of X and sketch its graph. (4 marks) (b) Find the probability that the machine dispenses: (i) less than 183 ml. (2 marks) (ii) exactly 183 ml. (2 marks) (c) Calculate the inter-quartile range of X. (6 marks) (d) Determine the value of x such that P(X2 x) = 2P(X <x) (6 marks)
