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. 3 4 5 6 7 X 8 9 10 P(X) 0.07 0.2 0.4 0.17 0.05 0.05 0.04 ? (a) Is X a discrete or continuous random variable? (Type: DISCRETE or CONTINUOUS) ANSWER: discrete (b) What must be the probability of choosing a unit with 10 rooms? P(X = 10) = 0.02 (c) What is the probability that a unit chosen at random is not a 10-room unit? P(X = 10) - (d) What is the probability that a unit chosen at random has three rooms? P(X = 3) = || = (e) What is the probability that a unit chosen at random has between four and six rooms? P(4≤ X ≤ 6) =
