Answer:
1716
Step-by-step explanation:
here we have to form arrangements of 3 students
taken from 13 students.
• Where order is important because the positions President, Vice President and Treasurer are not the same.
• also ,repetition is not allowed ,because one student can’t occupy two positions at the same time.
Then ,the number of possible ways
is equal to the number of permutations :
= 13P3
= 13×12×11
= 1716
