The chance of an IRS audit for a tax return with over $25,000 in income is about 2% per year. We are interested in the expected number of audits a person with that income has in a 11-year period. Given that the population follows a binomial distribution, find the probability that a person is audited more than 4 times in a 11-year period. Round to four decimal places.

Please use excel b. A rookie is brought to a baseball club on the assumption that he will have a .300 batting average. (Batting average is the ratio of the number of hits to the number of times at bat.) In the first year, he comes to bat 300 times and his batting average is .267. Could such a low average be considered just bad luck or should he be sent back to the minor leagues? Assume that his at...
