Please help. I didn't get the right answer with this before.

A mathematics journal has accepted 14 articles for publication. However, due to budget restraints, only 7 articles can be published this month. How many specific ways can the journal editor assemble 7 of the 14 articles for publication?
Possible answers:
14
3,432
98
17,297,280

  • Statistical probability411 - ,

    14C7=14!/(7!7!)
    ! means factorial
    7!=7×6×5×4×3×2×1

  • Statistical probability411 - ,

    If order is not important
    14C7=14!/(7!7!)
    ! means factorial
    7!=7×6×5×4×3×2×1
    If order is important, which is not explicit in the question, then the answer is
    14P7=14!/7!
