Jenny is an elementary school student and her father Jack works near her school. Every day, Jack sends Jenny to school first, and then he drives to work. According the experience from the past, Jenny has 90% chance of being school on time, and Jack has 80% chance of arriving to work on time. However, when Jenny is late to school, Jack has 60% chance of being late to work. (a)In a particular day, what is the probability that both Jenny and Jack are late? (b)In a particular day, what is the probability that Jenny arrives school on time but Jack is late to work? (c)Is the lateness of Jenny and Jack independent? Why?

At a certain large company, the floor manager reviewing inventory and production. She ultimately comes to the decision that a product should be continued if it sold 150,000 times over the previous year. In addition, the product is considered “popular” if it receives at least 100 mentions by the local press over the past year. An analyst is hired to help with the analysis. The analyst determines that the probability of sales exceeding 150,000 was 0.331, the probability of 100 or more mentions was 0.162, and the probability that a product both sold 150,000 items, and was also ‘popular’ is 0.064. What is the probability that a randomly selected product either sold the requisite 150,000 items, or that it is ‘popular’? Again, phrase your answers in terms of probability variables (e.g. P(X) = ..., P(Y)=... etc.) If we are told that an item has indeed reached the threshold of 100 mentions in the press, what is the probability of it selling 150,000 times?

Joon wants to determine whether his San Jose oil field will yield oil. He has hired a geologist to run tests on the field. If there is oil in the field, there is a 95% chance that the test will indicate oil. If the field contains no oil, there is a 5% chance that the test will indicate oil. If the test indicates that there is no oil in the field, what is the probability that the field contains oil? Before the test, Joon believes that there is a 10% chance that the field will yield oil.

In automotive repair, experience has shown that a rough - running engine can be attributed to the bad ignition wires 35% of the time, bad spark plugs 80% of the time, and both problems 20% of the time. Suppose a mechanic begins to diagnose the problem by checking the spark plugs first and find them to be bad. Given this information, what is the probability that the wires are also bad?
A door-to-door salesman expects to make a sale 21% of the time when starting the day. But making a sale increases his enthusiasm so much that the probability of a sale to the next customer is 0.32. If he makes no sale, the probability for a sale to the next customer stays at 0.21. What is the probability that he will make at least two sales with his first three visits?
