The following chart shows the (approximate) total number of subprime home mortgages in a state in November 2008, broken down into four categories. Mortgage Status Current Past Due In Foreclosure Repossessed Total Number 156,330 58,310 8,550 5,590 228,780 (The four categories are mutually exclusive; for instance, "Past Due" refers to a mortgage whose payment status is past due but is not in foreclosure, and "In Foreclosure" refers to a mortgage that is in the process of being foreclosed but not yet repossessed.) (a) Find the probability that a randomly selected subprime mortgage in the state during November 2008 was neither in foreclosure nor repossessed. HINT [See Example 1.] (Round your answer to two decimal places.) (b) What is the probability that a randomly selected subprime mortgage in the state during November 2008 was not current? (Round your answer to two decimal places.)
