Mmhmm I couldn't say the same for u @johnweldon1993 lol ;P

anonymous · Answer

so four options, 1, 2, 3, 4 

so 4/6 = 2/3 

so there is a 66% chance of rolling a number 1 - 4.

so a bookmaker would try and make u bet at a price less than $1.51, or offer you 3-2 odds on, but only a fool would bet becuase it would be under the odds and u would lose long term. 

Never gamble at a casino, you will lose.

The even numbers or a multiple of three are:
