that is is not rural.
P(not rural) = 1-0.48 = 0.52
============================================

2)Suppose you choose an acre of land in Maryland at random. The probability is now 0.18 that it is urban and now 0.5 that it is rural. What is the probability that the acre chosen is either urban or rural?
P(urban or rural) = 0.18+0.50 = 0.68
