d) A professor uses two proofreaders Ali and Hana to check a certain manuscript. Ali misses 13% of typographical errors and Hana misses 9%. Assume that the proofreaders work independently. i. What is the probability that a randomly chosen typographical eror will be missed by both proofreaders? i. If the manuscript contains 2000 typographical errors, what number can be expected to be missed?

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
