Rocío y su hermano Rafael son aficionados al modelismo y tienen una colección de barcos y aviones. Rocío comentó: "Si tuviéramos once barcos más, tendríamos el mismo número de barcos y aviones", a lo que Rafael respondió: "Pero si tuviéramos doce aviones más, tendríamos el doble de aviones que de barcos". ¿Cuántos barcos y aviones tienen Rocío y Rafael?

i hope this is what you were looking for.

step-by-step explanation:

a cube has 6 sides

the probability of getting 5 on the first cube is 1/6 since only one side of the cube has 5 on it.

there are 3 sides of the cube with even number on it [2,4,6]

therefore the probability of getting even number is 3/6

for both events to happen together, the probability would be

1/6 x 3/6 = 12/36

which simplifies to 1/12
