Let's assume there's a fourth place too, and fourth place is the one where it's no prize.
4 3 2 1 (4 3 X X)
4 3 1 2 (^ but 3rd and 4th digit exchanged)
4 2 3 1 (4 2 X X)
4 2 1 3 etc.,.
4 1 2 3
4 1 3 2
As you can see, there are six possibilities assuming first swimmer was fourth.
Now, there would be six possibilities if the first swimmer was third, and same goes for second and first.
Thus, 6 x 4 = 24, there are 24 possibilities to award the 3 prizes (plus 1 no-prize)
Simple Mathematical Way:
4 x 3 x 2 x 1 = 4! = 24
There are 24 ways.

Answer:
Step-by-step explanation:
using the sine rule,
52 people like only musicals.
There are 212 people. We know that the only answers were only animated movies, only musicals, or both. We also know that 74 people like only animated movies, and 86 people like both. To find the number that like only musicals, subtract these from the total number of people:
212-(74+86) = 212-160 = 52
the asnwer will be 7 cuz -7/-1
