Consider two urns: Urn-1 contains 3 red, 2 black and 4 white balls while Urn-2 contains 4 red, 4 black and 3 white balls. An urn is randomly selected with equal chances of it being Urn-1 or Urn-2, and then a ball is picked at random from the selected urn. (a) Find the probability that either a white or a red ball is picked? Your answer correct up to four decimal places. (b) If the picked ball is NOT black, find the probability it came from Urn-2? Your answer correct up to four decimal places.
An analyst is presented with lists of 4 stocks and 5 bonds. He is asked to predict, in order, the 2 stocks that will yield the highest return over the next year and the 2 bonds that will have the highest return over the next year.
