Answer:
Se pueden formar 9 números pares.
Step-by-step explanation:
Dado que con cuatro cartas se pueden formar diferentes números, como por ejemplo 8232 o 3822, para determinar cuántos números pares de cuatro dígitos y diferentes puedes formar con estas cuatro cartas se debe realizar la siguiente tabla:
8232 - 8322 - 8223 = 2 pares 1 impar
2832 - 2823 - 2382 - 2328 - 2283 - 2238 = 4 pares 2 impares
3822 - 3282 - 3228 = 3 pares
Por lo tanto, se pueden formar 9 números pares.
