The number of combinations of a president, vice president, secretary and a treasurer can be chosen from a group of 12 students is 11,880.
Given: we have group of 12 students.
we are asked to determine the number of combinations of a president, vice-president, secretary, and treasurer can be chosen from a group of 12 students.
nPr = n!/(n-r)!
12P4 = 12!/(12 - 4)!
12P4 = 12!/8!
9 × 10 × 11 × 12
= 11,880
Hence the number of combinations are 11,880.
