In this problem, it is said that four accounting majors, two economics majors, and three marketing majors have interviewed for five different positions at a certain company, and we need to find the number of different ways that five of these could be hired if the four accounting majors must be hired first, and then the final position is chosen from the remaining majors.

So we have a total of five different positions.
00:23
Now, the first position will be an accounting major.
00:28
It will be given to an accounting major because the first, the first, the first, the first, four accounting majors must be hired first.
00:33
So there are four options to choose from for this first position.
00:37
Now, the second position is also going to be given to an accounting major, and it will be given to any one of those four accounting majors except for the one who already got this first position.
00:46
So that's four minus one a total of three options to choose from when selecting which major accounting major to give this position too.
