Since the wording of this question says "how many ways can he list his courses" the order in which they are picked does matter right?

anonymous · Answer

So I use the permutation 6*5*4*3=360 For his major disciplines

anonymous · Answer

three of the four courses=4*3*2=24
Therefore the order in which he can list the course equals to 360*24=8640
