Answer:

120 maneras distintas

Step-by-step explanation:

En esta pregunta, tenemos 5 hombres y 4 mujeres. El número total de ubicaciones es 5 + 4 = 9 ubicaciones

Las posibles posiciones para colocar todo son las siguientes '

1 2 3 4 5 6 7 8 9

Ahora, las mujeres están tomando las posiciones pares que son 2 3 4 y 8

Las posiciones restantes que quedan sin ocupar serán posiciones;

Ahora, cada uno de los 5 hombres puede seleccionar solo una posición a la vez.

El primer hombre tiene 5 opciones, el segundo hombre tiene 4 opciones, el tercer hombre tiene 3 opciones, el cuarto hombre tiene dos opciones mientras que el último hombre tiene una sola opción. ¡Por lo tanto, la cantidad de formas en que será posible la disposición de la sesión es simplemente 5! maneras = 5 * 4 * 3 * 2 * 1 = 120  formas
