Answer:

3 formas

Step-by-step explanation:

Se nos pide que averigüemos cuántas formas puede utilizar para cruzar un río si tiene 1 bote y 2 barcos

Número total de barcos = 3 barcos.

Resolvemos esto usando la regla de combinación.

C (n, r) = nCr = n! / R! (n - r)!

n = Número de barcos = 3

r = Número de ríos = 1

3C1 = 3! / 1! (3 - 1)!

= 3! / 1! × 2!

= 3 × 2 × 1/1 × 2 × 1

= 3 formas.

Por lo tanto, el número de vías por las que puede cruzar un río utilizando 1 bote y 2 barcos es de 3 formas.
