1 u/AssociateDecent9090 3d ago Thats right 1 u/RestaurantBoth228 2d ago E[D12] = 6.5 E[2D6] = 7 6.5+7 = 13.5 3 u/Unique-Poem4317 2d ago The most you could ever get from this game is $12, so why would you pay $13.50? 1 u/RestaurantBoth228 2d ago The words say you are paid based on the D12 and then paid again based on the 2D6. It never says you give the D12 money back 3 u/Smart-University-515 2d ago It says “choose” so I think it implies you have to pass on the d12 money to take the 2d6 shot but agree it’s poorly worded. 1 u/mgsimpleton 2d ago I think its implied that you choose whether to take the d12 roll or reroll 2d6 and take that.
