# Forum:SLASH'EM Mall - maximum number of shops?

Does anyone know what the maximum number of shops in the SLASH'EM mall is? I have the probability table list that shows the maximum theroretical number of shops is 11, and the level layout has room for 11 shops. But in reality the most I've seen is 6. Maybe someone who knows more about combinatronics & statistics can calculate the total probability of getting any given number of shops. Here's the probability table:

General - 100% Tool - 20% Food - 40% Scroll- 20% Potion - 30% Ring - 12% Lighting - 33% Book - 12% Wand - 17% Weapon - 20% Armor - 22% --Preceding unsigned comment added by Alpheus (talkcontribs) 13:47, 29 October 2013

It should obviously be possible for 11 shops to be generated, but it's not very likely. These should be the probabilities, unless I made some mistake:
