probability or a calculate method??

[tarek12]

i have three Tanks of oil storage
i want to exploit its with 2 differents products ( full , then empty them continually )
i have to respect this order for any Tank and any product
from 0h to 197 ( time of filling ), then 58 h to empty the tank
but directly after the first 197h i need to switch the tank
how i can calculate the probability to use the three tanks with out intersection
is there any methode or idea about a graph can facilitate the calcul
