(6 points) In a small town, all households have at most 3 cars. 26% of all households have no cars, 37% have 1 car, 21% have 2 cars and the rest have 3 cars. Suppose a household is randomly selected and let X be the number of cars the randomly selected household has. Part A Determine the probability distribution of X by completing the table below. Note Write all X values in an increasing order and round the probabilities to 5 decimal places (0.12345) if possible)
Part A Determine the probability distribution of X by completing the table below. Note Write all X values in an increasing order and round the probabilities to 5 decimal places (0.12345) if possible) Part B Calculate the expected value of X. (Round the expected value to 5 decimal places if possible) Part C Calculate the standard deviation of X (Round the standard deviation to 5 decimal places if possible) X Part D Calculate the probability that the household has at least 1 car (1 or more). (Round the probabilities to 5 decimal places if possible) Part E Calculate the probability that the household has at most 2 car (1 or less). (Round the probabilities to 5 decimal places if possible) Probability
