Answer:
Step-by-step explanation:
Let number of items
Let total expenditure
There are total 600 number of ways or permutations the top two finishers can be determined.
According to the given question.
Total number of people who are participating in a race = 25
In 25 participants the total number of participants to be selected to finish the race = 2
As we know that "a permutation is a mathematical calculation of the number of ways a particular set can be arranged, where the order of the arrangement matters". Which can be calculated as
Where,
is the number of permutations
n is the total number of objects
r is the numbers of objects to be selected
Thereofore,
The total number of ways, or permutaions the two top finishers can be determined is given by
= 25!/(25-2)!
= 25!/23!
= 25 × 24 × 23!/23!
= 25 × 24
= 600
Hence, there are total 600 ways or number of permutations the top two finishers can be determined.
