You might prefer to bet one dozen instead of one split. Some patterns may be easier to see than other patterns.
But if you compare chances, you may be rewarded with greater insight.
A small mathematical challenge for you:
At a roulette table with 37 numbers one guest is begging for dozen 1-12 to appear twice, say two times in the two NEXT spins.
Another guest hopes that split 33-36 appears WITHIN these following two spins. One time or two times.
WHAT DIFFERENCE DOES IT MAKE?
