The chair of an academic department needs to form 3 search committees each consisting of 5 tenured full professors. If the department has 18 such faculty, how many choices does the chair have if he decides that no one can serve on more than one search committee?

4314. In a large university with k academic departments, we must appoint an impor- tant committee. One professor will be chosen from each department. Some professors have joint appointments in two or more departments, but each must be the designated representative of at most one department. We must use equally many assistant profes- sors, associate professors, and full professors among the chosen representatives (assume that& is divisible by 3). How can the committee be found?

What’s the probability there are exactly two associate professors on the committee? b. What’s the probability all three professors on the committee have a different rank (that is, the committee contains one assistant, one associate, and one full professor)? c. What’s the probability all three professors on the committee have the same rank?

Suppose a mathematics department has 4 full professors, 8 associate professors, and 3 assis- tant professors. How many ways are there to select a 4-person curriculum committee if (a) at least one full professor is chosen? (b) the committee contains at least one professor of each rank? Suppose, as well, that a 3-person recruitment committee must also be selected. How many ways are there to select both committees if (c) there are no restrictions?

A student went around the math department and asked the professors how many tattoos they have when taken as a fraction of the total body surface area, (for instance a full back tattoo would be 1/4 body coverage) the student found that the median for the tattoo coverage was 3/10 but the mean was 3/5. What could explain this difference.
