A company audit reveals that 3% of the department budgets contain errors. A programis developed to analyze budgets and, in a test, identifies errors in 99% of budgets witherrors and 2% of those without. If a budget is identified by the program as possiblyhaving an error, what is the probability that the budget does have an error? (Hint: Usethe tree diagram, check out the examples in the Bayes' theorem notes)

In recent years research suggests that cell phone usage during social interactions leads to distractions, which undermines the benefits of social interaction. A recent report by greater good magazine reports that a survey shows that 82% of people report that the use of cell phones during a conversation decreases the quality and what they talk about. Assuming the greater good magazine report is accurate, and then a random sample of cell phone users during A recent conversation were sampled. You are interested in the probability that a specific number of the cell phones users would report that the use of cell phones during a conversation decreases the quality of what they talk about.
