O 0.16 O 0.36 O 0.2 O 1Mike Wilde is president of the teachers’ union for Otsego School District. In preparing for upcoming negotiations, he is investigating the salary structure of classroom teachers in the district. He believes there are three factors that affect a teacher’s salary: years of experience, a teaching effectiveness rating given by the principal, and whether the teacher has a master’s degree. A random sample of 20 teachers resulted in the following data.

- 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 = 68/102Find the probability that the person prefers hiking on the coastline given that the person is a female.?(??? ?????????│??????) =A student was given a TRUE or FALSE quiz consisting of 10 items.
