Someone over on the borderlands wiki rolled the same slot machine over 2,500 times in a row, documented the results of each spin, and then crunched the numbers into percentages as to what percentage chance a player has of getting each symbol per spin.
The chances of hitting triple vault symbols ended up being 0.04%.
Or 1 in 2,500 spins, to be exact.
