Of the light bulbs made by Acme, 7% are defective. Only 2% of the light bulbs made by Baker are defective. An office buys over 1000 light bulbs per year. They order 75% of their bulbs from Acme and 25% from Baker. A light bulb is chosen at random and found to be defective. What is the probability that it was produced by Baker?

Suppose that 3% of all athletes are using the endurance-enhancing hormone EPO (you should be able to simply compute the percentage of all athletes that are not using EPO). For our purposes, a “positive” test result is one that indicates presence of EPO in an athlete’s bloodstream. The probability of a positive result, given the presence of EPO is .99. The probability of a negative result, when EPO is not present, is .90. What is the probability that a randomly selected athlete tests positive for EPO? 0.0297

Aretha wanted to gather data about the cost of local bowling leagues in her area. She plotted the data and determined that the average bowling league costs consist of a one-time registration fee and a monthly fee modeled by the equation y = 15x + 20.Identify and interpret the y-intercept in this model. The y-intercept is 20. This is the cost per month. The y-intercept is 20. This is the cost of registration. The y-intercept is 15. This is the cost of registration. The y-intercept is 15. This is the cost per month.

Michael has never taken a foreign language class, but is doing a story on them for the school newspaper. The school offers French and Spanish. Michael has a list of all 25 kids in the school enrolled in at least one foreign language class. He also knows that 18 kids are in the French class and 21 kids are in the Spanish class. If Michael chooses two kids at random off his list and interviews them, what is the probability that he will be able to write something about both the French and Spanish classes after he is finished with the interviews? Express your answer as a fraction in simplest form.
