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.  Please enter all probabilities as a decimal rounded to 2 decimal places. X 3 4 5 6 7 8 9 10 P(X=x) 0.08 0.20 0.43 0.16 0.03 0.05 0.04 ? (a) Is x a discrete or continuous random variable? (Type: Discrete or Continuous) (b) What is the probability of choosing a unit with 10 rooms? P(X=10) (c) What is the probability that a unit chosen at random has more than 5 rooms? P(X>5) (d) What is the probability that a unit chosen at random is NOT a 10-room unit? P(X not equal 10) (e) What is the probability that a unit chosen at random has three rooms? P(X=3)
