Let the random variable X be the number of rooms in a randomly chosen owner-occupied housing unit in a certain city. The distribution for the units is given below. X 34 5 6 7 89 10 P(X) 0.09 0.29 0.34 0.15 0.05 0.04 0.02 ? (a) Is X a discrete or continuous random variable? (Type: DISCRETE or CONTINUOUS) ANSWER: (b) What must be the probability of choosing a unit with 10 rooms? P(X = 10) = (c) What is the probability that a unit chosen at random has three rooms? P(X = 3) = (d) What is the probability that a unit chosen at random has more than 5 rooms? P(X > 5) = (e) What is the probability that a unit chosen at random is not a 10-room unit? P(X + 10) = Note: You can earn partial credit on this problem. preview answers
