To find the number of ways all 13 students can be ordered in line, we can use the formula for permutations of a set of objects. The number of ways to arrange 'n' objects is given by n!, where n! represents n factorial.

1. Number of ways all 13 students can be ordered in line:
13! = 13 \times 12 \times 11 \times \ldots \times 2 \times 1 = 6,227,020

2. Number of ways 3 students can be ordered in line out of 13:
We can use the same formula for permutations, but this time we pick 3 students out of 13 to find the number of ways they can be arranged.
^{13}P_3 = \frac{13!}{(13-3)!} = \frac{13!}{10!} = 13 \times 12 \times 11 = 1,716

\textbf{Answer:}
1. There are 6,227,020 ways all 13 students can be ordered in line.
2. There are 1,716 ways 3 students can be ordered in line out of 13.
