A tax specialist has estimated that the probability that a tax return selected at random will be audited is 0.04. Furthermore, he estimates the probability that an audited return will result in additional assessments being levied on the taxpayer is 0.60. What is the probability that a tax return selected at random will result in additional assessments being levied on the taxpayer?

One out of every 119 tax returns that a tax auditor examines requires an audit. Find the probability that (a) the first return requiring an audit is the 25th return the tax auditor examines, (b) the first return requiring an audit is the first or second return the tax auditor examines, and (c) none of the first five returns the tax auditor examines requires an audit.
