(a) Of 500 car parts produced, it is known that 350 parts are produced in one plant, and 150 parts in a second plant. Also it is known that the probabilities are 0.15, and 0.2 that the parts will be defective if they are produced in the first and second plants, respectively. What is the probability that a randomly picked part from this batch is not defective? 3 Marks (b) An urn contains 4 red balls, 3 blue balls, and 6 white balls. A ball is selected and its colour noted, then it is not replaced. A second ball is selected and its colour noted. Find the probability of selecting one red ball and then one white ball. 2 Marks
