A professor teaches two sections of a course:
• 70% of students are in Section 1, and 30% are in Section 2.
•
In Section 1, 90% of students pass the final exam.
•
In Section 2, 80% of students pass the final exam.
A student is randomly selected.
a) Draw a tree diagram to represent this situation.
b) What is the probability that the selected student passes the exam?
c) Given that a student failed, what is the probability they were from Section 1?
.. A factory has two machines, A and B. Machine A produces 60% of the parts, while Machine B
produces 40%. Machine A produces defective parts 5% of the time, while Machine B produces defective
parts 10% of the time. A randomly selected part from production is inspected.
a) Draw a tree diagram to represent the probability of getting a defective part.
b) What is the probability that a randomly selected part is defective?
c) If a part is found to be defective, what is the probability it came from Machine A?
A Factory produces light bulbs from two different machines: Machine A and Machine B. The
probability that a randomly selected light bulbs is from Machine A is 60%, and the probability that a light
bulb is defective is 5%. Suppose that probability that a light bulb is defective given that it was made by
Machine A is 0.05. Similarly, the probability that a light bulb is defective given that it was made by
Machine B is 0.03. Are the events “the light bulb is from Machine A” and “the light bulb is defective”
independent?
