Answer:
1320
Explanation:
To find the number of ways to select a secretary, vice-president, and treasurer from a group of 12 candidates, we can use the permutation formula:
=> nPr = n! / (n - r)!
where n is the total number of candidates, and r is the number of positions to fill (in this case, r = 3).
Plugging in the values, we get:
12P3 = 12! / (12 - 3)!
=> 12! / 9!
=> 12 x 11 x 10
=> 1320
Hence, there are 1320 ways to select a secretary, vice-president, and treasurer from 12 candidates.
