Final Answer:
There are 1,716 ways for the teacher to assign these tasks to the students.
Step-by-step explanation:
Since each task (line leader, wiping down tables, passing out papers) can only be assigned to one student at a time, we can use the multiplication principle to find the total number of ways to assign these tasks.
For the first task (line leader), there are 13 students to choose from. Once the line leader is chosen, there are 12 students left for the second task (wiping down tables), and for the third task (passing out papers), there are 11 students left.
So, the total number of ways to assign the tasks is:
13×12×11=1,716 ways.
Therefore, there are 1,716 ways for the teacher to assign these tasks to the students.
