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
For the given pair of events, classify the two events as independent or dependent. Getting caught in traffic Spilling coffee in the car Choose the correct answer below. A. The two events are independent because the occurrence of one does not affect the probability of the occurrence of the other. B. The two events are dependent because the occurrence of one does not affect the probability of the occurrence of the other. C. The two events are independent because the occurrence of one affects the probability of the occurrence of the other. D. The two events are dependent because the occurrence of one affects the probability of the occurrence of the other.
