I have some combination questions:
(a) The Mathematics departmental office has the following stock of
dryerase markers: 7 Red, 4 Navy blue, 6 Green, 8 Black. They are
to be distributed, 1 apiece, to the 25 members of the department. How many outcomes are possible?
(b) The Chemistry departmental office has 800 black dryerase markers. The 25 members of the department may take as many as they like. If 46 markers are taken the ﬁrst day, how many different distributions to the faculty members are possible?
