Answer:
The area 2730 possible arrangements of first, second, and third place.
Step-by-step explanation:
The order in which the students finish is important. For example A, B and C is a different finishing order(outcome) than B, A and C. So we use the permutations formula to solve this question.
Permutations formula:
The number of possible permutations of x elements from a set of n elements is given by the following formula:

In this question:
3 from a set of 15. So

The area 2730 possible arrangements of first, second, and third place.

Answer:
4 bottles
Step-by-step explanation:
Let o represent the number orange juice bottles Megan bought. Then the total number of juice bottles is ...
