Answer:
1320
Step-by-step explanation:
We are given that
Total number of athelets are running in race=12
Total number of medals =3
We have to find the total possible number of ways can the 3 medals be distributed.
Total number of ways for choosen gold medal=12
Number of ways for choosen silver medal=11
Number of ways for choosen Bronze medal=10
Total number of possible ways=![12\times 11\times 10=1320](https://tex.z-dn.net/?f=12%5Ctimes%2011%5Ctimes%2010%3D1320)
Hence, total number of possible ways in which 3 medals be distributed=1320
