On his university application, Prashad must list his course choices in order of preference. He must choose four of the six courses available in his major discipline and three of the four courses offered in related subjects. In how many ways can Prashad list his course choices?

    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?

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

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

    here is my best guess |dw:1437286293253:dw| multiply the choices for major and minor together for the answer

    the only thing not mentioned is whether he must choice the major course before the minor course if is order isn't important in the way major ore minor are selected.

    the use of "list" borders nominal or ordinal

    then ther maybe 2 ways of slecting the courses as a multiplier to your answer
