A psychological test has scores that range from 0 to 10 (whole numbers only). The stable range is given by scores ranging from 3-8 (inclusive); the group scoring less than 3 are labeled as Low Risk, while those with a score greater than 8 are labeled as High Risk. In a certain population of interest, the probability that a person is psychologically stable is 86%, and the probability that a person is from the High Risk group is 4%. A random sample of 10 people is taken from this population. What is the expected number of people NOT from the stable group? Question 9 options: 0.14 14.0 1.40 8.60 None of the above
