Eighteen individuals are scheduled to take a driving test at a particular dmv office on a certain day, eight of whom will be taking the test for the first time. suppose that six of these individuals are randomly assigned to a particular examiner, and let x be the number among the six who are taking the test for the first time. (a) what kind of a distribution does x have? specify all parameters. (b) compute p(x = 2), p(x ≤ 2) and p(x ≥ 2). (c) calculate the mean and standard deviation of x.
