Following a major earthquake, a team of engineers visited a city to assess whether or not buildings constructed under the new earthquake safety guidelines had fared better than older buildings. Every building in a 6 square block downtown area was inspected, and the following results were obtained. New Construction Old Construction Total No significant damage 18 75 93 Moderate damage 26 57 83 Severe damage 24 62 86 Total 68 194 262 One of these buildings is selected at random, find the probability that the selected building a. has no significant damage, b. has no significant damage, given that it is of new construction, c. has severe damage, d. has severe damage, given that it is of old construction.
