Question 9. Suppose we have thirty balls divided into three groups of ten by color (green, red,blue). Per color, each ball is numbered from 0 to 9. All balls are put into a sealed box wherepeople can draw three at a time without looking, making the choice random. Compute theprobability ofa. Choosing three red ballsb. Choosing one blue ball and two green balls regardless of their sequencec. Choosing one red ball, one blue ball, and one green ball in sequence

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
