| SammyJankis Member since: Feb 8, 2010 Threads: 6 Posts: 16 | Before a number rolls, if i were to call the 6 for example, what would the odds be of hitting it back to back. Is it just 38 x 38? 1 of 1444. Or 1443 to 1 |

| DJTeddyBear Member since: Nov 2, 2009 Threads: 92 Posts: 4929 | Yeah, there's nothing mystical about it. The odds of hitting any specific number is 1/38 (or 1/37 for single zero wheels). Call that 'X' The odds of hitting the number twice in a row is x ^ 2. The odds of ANY repeat (i.e. simply seeing a repeat pop up on that display board) is x. The odds of ANY three-peat (i.e. seeing a three-in-a-row on that display board) is x ^ 2. Superstitions are silly, childish, irrational rituals, born out of fear of the unknown.
But how much does it cost to knock on wood? |

Those would be the odds before any specific number hit the first time. Once a number has hit, it is 1/38 it will repeat. |

| pacomartin Member since: Jan 14, 2010 Threads: 508 Posts: 5166 | While the odds are 1 : 1444 (38*38) the odds of it happening at least once in slightly over 1027 spins are 50% . So over the course of a day it is probably going to happen at least once. Wine loved I deeply, dice dearly -Edgar, betrayed son of Gloucester in King Lear |
