Respuesta :
Melanie has 3 posters she wants to hang on the wall. so, the number of ways f hang the posters will be gotten by the factorial method is 6.
How does factorial work?
Factorial of a positive integer is the result of the repeated multiplication of all the integers from 1 to that considered integer.
Thus, if we want to take factorial of 'n',(n being a positive integer), then:
[tex]n! = 1 \times 2 \times \cdots \times (n-1) \times n[/tex]
The points are to be arranged in the room without any definite pattern or configuration.
Since there is no definite pattern or configuration to hang the posters, the number of ways f hang the posters will be gotten by the factorial method.
A number of ways = 3!
= [tex]3\times 2\times 1\\\\ 6\\[/tex]
