The probability that it will rain on any given day is 0.20, and the probability is independent from day to day. You are trying to decide whether or not to make a tee time tomorrow to play golf. This requires a commitment on your part of turning down, say, movie tickets in favor of playing golf. If you accept the tickets, you also make the commitment not to go golfing. There is a weather forecast that signals whether it will rain tomorrow or not. There is a 0.80 probability that it rains when there is a "rainy" forecast and a 0.125 probability of rain when there is a "sunny" forecast. The overall probability of getting a "rainy" forecast is 0.111. Assume you are risk neutral. You place the following monetary values on the potential outcomes: a sunny day at the golf course a rainy day at the movies a rainy day at home $95 $20 -$18 a sunny day at $1 the movies a. If you have no weather forecast, evaluate the expected value of planning to golf and planning to go to the movies. What is the…

A study at a college on the west coast reveals that, historically, 36% of thestudents are minority students.

Among 7610 cases of heart pacemaker malfunctions, 405 were found to be caused by firmware, which is software programmed into the device. If the firmware is tested in 3 different pacemakers randomly selected from this batch of 7610 and the entire batch is accepted if there are no failures, what is the probability that the firmware in the entire batch will be accepted? Is this procedure likely to result in the entire batch being accepted? The probability is. This procedure is (Round to three decimal places as needed.) to result in the entire batch being accepted. C

A student takes an exam containing 20 multiple choice questions. The probability of choosing a correct answer by knowledgeable guessing is 0.3. At least 13 correct answers are required to pass. If the student makes knowledgeable guesses, what is the probability that he will fail? Round your answer to four decimal places.

When a new machine is functioning properly, only 6% of the items produced are defective. Assume that we will randomly select two parts produced on the machine and that we are interested in the number of defective parts found. (a) Describe the conditions under which this situation would be a binomial experiment. (Select all that apply.) For each part selected, the probability of a defective part being produced must be 0.06. The parts must be selected independently. The selection of a part is dependent on the first part selected. The number of successes and failures in this experiment are equal. The probability of choosing a part that is defective must be 0.94. (b) Draw a tree diagram similar to this section's example showing this problem as a two-trial experiment. Tree Diagram Description ---Select--- ---Select--- ---Select--- ---Select--- Not Defective Defective ---Select--- Not Defective ---Select--- ---Select--- O O O 0 O
