How many ways can 6 people line up for a race. This is is a combination, but I do not know how to solve it. Help is appreciated.
The answer is 6!
6 factorial.
You multiply 6 x 5 x 4 x 3 x 2 x 1.
720
To find the number of ways 6 people can line up for a race, we will use the concept of permutations, which represents the arrangement of objects in a specific order.
To solve this problem, we can use the factorial notation (!). The factorial of a number is the product of all positive integers less than or equal to that number.
In this case, since we have 6 people, we need to find the factorial of 6, which is denoted as 6!.
Calculating 6!:
6! = 6 x 5 x 4 x 3 x 2 x 1 = 720
Therefore, there are 720 different ways that 6 people can line up for a race.
