A sports club with 30 members wishes to pick a president, vice-president, secretary, and treasure. Assuming that no person can hold two offices, in how many ways can the selections be made? I have used the "counting principle" as the book suggested 30x29x28x27. I also tried using the permutation formula 30!/(30-4)!. HELP! I have been trying to solve this problem for two days.
