2nd because you have some pieces on the board to work with.
There is no "official' list of odds anywhere. At each track the handicapper(s) take their best guess and these are the odds printed in the program. But the betters set the real odds with their bets. The more money bet on a horse, the shorter the odds. Basically, at the track, all the money bet goes into a pool. The taxman and the track take their cut and what is left is the money that can be won. There is a sum of money (a pool) for first, a pool for second and a pool for third. A bet for second pays if the horse comes first or second. A bet for third pays if the horse finishes first or second or third. Bets with off track bookies are different. You are quoted odds at the time you place your bet and regardless of what else happens, if you win, you get paid at those odds.
Odds of rolling seven once (2 dice) is 1:6, twice in a row, odds are 1:36. The reason is- the first die can be any number, but the second die must be a particular number. For example, if the first die is 6, then the second die has to be 1 to make 7. When an event occurs twice, and the two events are unrelated, then you can multiply the odds together= 1/6 * 1/6 = 1/36.
An exacta is a type of bet where you pick the horses who will finish first and second, in that order ("exact").
Odds od 3-1 would pay out more.
To roll a 7, it doesn't matter what your first die rolls at, as every number on the die has a complement that will add up to 7. This means that your odds on rolling 7 are actually your odds on rolling the appropriate number on the second die. ie. 1/6. No matter what your first die is, the second can potentially give you a number that brings the total to 7. To roll an 11 however, your odds are not as high. This is because you must roll a five and a six to hit 11. Your first die can be either of the two, but your second die must be it's complement. In this case then, your odds are 2/6 * 1/6, or 1/18.
There are no odds. It just happens.
The most important poker odds to memorize for improving your game are the odds of hitting certain hands like a flush or straight, the odds of winning with certain starting hands, and the odds of your opponents having better hands than you. Understanding these probabilities can help you make better decisions during a game.
In order to get a ten, your first die must be either a 4, 5, or 6. The odds on that happening are 3/6, or 1/2. Your second die must then equal six minus the first die. Your odds on that are 1/6. Your overall odds then are 1/2 * 1/6, or 1/12.
