Based on a survey, assume that 30% of consumers are comfortable having drones deliver their purchases. Suppose we want to find the probability that when six consumers are randomly selected, exactly four of them are comfortable with the drones. What is wrong with using the multiplication rule to find the probability of getting four consumers comfortable with drones followed by two consumers not comfortable, as in this calculation (0.360.36x0.38x0.36x0 64x0.64) 0.00007 Choose the correct answer below with drones OA. The event that a consumer is comfortable with drones is not mutually exclusive with the event that a consumer is not cortable v OB The calculation assumes that the first four consumers are comfortable with drones and the last two are not, but this arrangement is not possible. OC. The probability of the second consumer being comfortable with drones cannot be treated as being independent of the probability of the first consumer being comfortable with drones OD There are other arrangements consisting of four consumers who are comfortable and two who are not. The probabilities corresponding to those other arrangements should also be included in the result
