a. What is the probability that a randomly selected housing unit has at most 4 rooms?:::0.005+0.012+0.104+0.210 = 0.331
----------
b. What is the probability that a randomly selected housing unit has at least 5 rooms?:::0.218+0.190+0.122 = 0.53
----------
c. What is the probability that a randomly selected housing unit has more than 7 rooms?::: 1 - [0.331+0.219+0.190+0.122] = 0.138
