Likelihood of Selecting a Favorite Less Likely (0) Somewhat Likely (1) Likely (2) 0.35 Probability 0.04 0.08 More Likely (3) 0.38 Most Likely (4) 0.15 (a) Find the probability that the selections range from somewhat likely (1) to most likely (3), including the likely (2) state. (b) Find the probability that the selection is not less likely (0). Q(19) Discrete probabilities (continued); Consider Q(18) above. (12 points) (a) Find the probability that the selections are not likely (2). (b) Find the probability that the selection is not most likely (0).
