Complemental Probabilities

A few sample problems from Ask Marylyn

Suppose 95% of a given population are not drug users and that a drug test has a 95% chance of returning the correct result. a) What is the probability an individual chosen at random from the given population will test positive for drugs? b) Given that an individual from this population has tested positive for drugs, what is the probability that the person uses drugs? c) What is the probability that a non- drug user will test positive?

Binomial Distributions A Probability Experiment

1. Due 12/6 Play with either the Game of Life or the Chaos Spreadsheet, experiment with it, attempt to answer the questions provided in either the spreadsheet or questions.txt and write an essay discussing what you found. 2. Experiment with the compound interest spreadsheet. Approximately what would your payments be if you borrowed $100,000 at 5% interest compounded continuously? Due 12/6 Read Sections 7.1 and 7.2 complete mindscapes 11, 38 and 41 from section 7.2. Typo on paper due date 11/29 is TUESDAY not THURSDAY
