Question
Piper is organizing textbooks on her bookshelf. She has a Spanish textbook, a biology textbook, a history textbook, and a writing textbook. How many different ways can she line the textbooks up on her bookshelf?
Solution
Piper tiene 4 libros diferentes que puede organizar en su estantería. El número de formas en que puede organizar estos libros se puede calcular utilizando la fórmula de permutación n!, donde n es el número de libros.
En este caso, n es 4 (español, biología, historia, escritura), por lo que la permutación sería 4!
4! = 4 x 3 x 2 x 1 = 24
Por lo tanto, Piper puede organizar sus libros de texto en 24 formas diferentes en su estantería.
