Math/Logic Test for Musicians

This is apparently floating around the St. Louis Symphony (must not have any Rouse on the program this week). Don't know where they got it. Enjoy:

Math/Logic Quiz

1. Wilson is tired of paying for clarinet reeds. If he adopts a policy of playing only on rejected reeds from his colleagues will he be able to retire on the money he has saved if he invests it in mutual bonds, yielding 8.7%, before he is fired from his job? If not, calculate the probability of his ever working in a professional symphony orchestra again!

2. Jethro has been playing the double bass in a symphony orchestra for 12 years, three months and seven days. Each day, his inclination to practice decreases by the formula: (total days in the orchestra) x 0.0076. Assuming he stopped practicing altogether four years, six months and three days ago, how long will it be before he is completely unable to play the double bass?

3. Wilma plays in the second violin section, but specializes in making disparaging remarks about conductors and other musicians. The probability of her making a negative comment about any given musician is 4 chances in 7, and for conductors is 16 chances out of 17. If there are 103 musicians in the orchestra and the orchestra sees 26 different conductors each year, how many negative remarks does Wilma make in a two-year period? How does this change if five of the musicians are also conductors? What if six of the conductors are also musicians?

4. Horace is the General Manager of an important symphony orchestra. He tries to hear at least four concerts a year. Assuming that at each concert the orchestra plays a minimum of three pieces per concert, what are the chances that Horace can avoid hearing a single work by Mozart, Beethoven or Brahms in the next ten years?

5. Betty plays in the viola section. Despite her best efforts she is unable to play with the rest of the orchestra and, on average, plays 0.3528 seconds behind the rest of the viola section, which is already 0.16485 seconds behind the rest of the orchestra. If the orchestra is moving into a new concert hall with a reverberation time of 2.7 seconds, will she be able to continue playing this way undetected?

6. Ralph loves to drink coffee. Each week he drinks three more cups of coffee than Harold, who drinks exactly one third the amount that the entire brass section consumes in beer. How much longer is Ralph going to live?

7. Rosemary is unable to play in keys with more than three sharps or flats without making an inordinate number of mistakes. Because her colleagues in the cello section are also struggling in these passages she has so far been able to escape detection. What is the total number of hours they would all have to practice to play the complete works of Richard Strauss?
