Question 4

Use the graphic from the previous question to answer the following:

Because this is a required course at his school, Mr. Garza's classes filled up before Zane told his counselor which time of day he prefered. The school decides to add an additional teacher, Ms. Lopez, who will teach the computer class 1st and 6th periods. Does this affect the probability of getting Mr. Nelson in the morning? Be very specific in explaining any and all affects this has on the probability.

The school counselor asks Zane if he prefers a morning or afternoon class. Below is a list of teachers and the periods they teach this class. The morning classes are 1st, 2nd, and 3rd periods, and the afternoon classes are 4th, 5th, and 6th periods. Mr. Nelson-2nd, 4th, 5th, 6th Ms. Trevino-1st, 2nd, 3rd, 4th, 5th Mr. Garza-1st, 3rd, 4th, 6th Ms. Jones-1st, 2nd, 3rd, 6th 1. Before answering the counselor's question, Zane wants to list all the possibilities so he can make a choice that gives him the highest probability of getting a teacher he prefers.

Explanation & Answer

The solutions are ready, please ask if something is unclear.

3. This means going along the miss line (0.7) AND then hit line (0.3), so the probability is
0.7*0.3 = 0.21.

5. Terminated probably means "GAME OVER"/ It requires miss (0.7) AND miss again (0.7),
the probability is 0.7*0.7 = 0.49.

6. There are two paths to repeat level 1: miss AND hit, 0.7*0.3 = 0.21; hit AND miss,
0.3*0.7 = 0.21. The answer is the sum of these probabilities, i.e. 0.42.

1. Again two paths, hit-hit-hit (0.3*0.3*0.3 ...
