A company produces scooters used by small businesses, such as pizza parlors, that find them convenient for making short deliveries. The company is notified whenever a scooter breaks down, and the problem is classified as being either mechanical or electrical. The company then matches the scooter to the plant where it was assembled. The file Scooters contains a random sample of 200 breakdowns. Use the data in the file and the relative frequency assessment method to find the following probabilities:
a. What is the probability a scooter was assembled at the Tyler plant?
b. What is the probability that a scooter breakdown was due to a mechanical problem?
c. What is the probability that a scooter was assem bled at the Lincoln plant and had an electrical problem? |
