In Tiny Dungeons 2e, the chance of Success when rolling with advantage ( roll all three d6) is 19/27, or ~70%.
Under normal circumstances, characters only get to roll 2d6, needing at least a single result of 5 or 6 to indicate a Success. The chances of this are 5/9, or ~56%.
Finally, the chance of Success when rolling with Disadvantage (only a single d6 must come up '5' or '6') is 1/3, or ~33%.
