Question

chemist who has five assistants is engaged in a research
project that calls for nine compounds that must be synthesized.
In how many ways can the chemist assign these syntheses to the
five assistants so that each is working on at least one synthesis?

Answer 1

is here any one

Answer 2

The first assistant can work on one of nine compounds. The second assistant can work on one of eight, because he can't work on the one that the first assistant is working on. The third has seven options, the fourth has six, and the fifth has five. Multiply all of those together (9*8*7*6*5) and there are 15120 possible ways to assign the assistants to the compounds.
