Observe the question below and the two possible solutions. State which solution is correct and give a reason for your choice. For a group of 300 cars the numbers, classified by colour and country of manufacture, are shown in the table.                   Black                              Silver                        WhiteKorea            33                                  34                              35Japan            23                                    9                              24America        16                                  25                              34Germany      19                                  16                              32 One car is selected at random from this group. Find the probability that the selected car is a black or white car manufactured in Korea. Solution 1 P (BUW) = P (B) + P (W)               = 33/300  + 35/300               = 68/300 Solution 2 P (BUW) = P (B) + P (W)               = 33/102  + 35/102               = 68/102
