Answer:
B: Permutation; Number of ways are 60
Step-by-step explanation:
At a competition with 5 runners, medals are awarded for first, second, and third places.
Each of the 3 medals is different.
This is a case of Permutation and the Number of ways are 60.
We have to award 3 medals among 5 runners.
This can be done in 5P3 ways.
= [tex]\frac{5!}{(5-3)!}[/tex]
= [tex]\frac{5\times4\times3\times2\times1}{2\times1}[/tex]
= [tex]5\times4\times3=60[/tex]
Therefore, the answer is option A.
