1. Forecasts
It's hard enough to select a winner so why make it more difficult and try find the second as well?
Consider that in every 6 runner race there are 30 possible forecasts:
1-2, 2-1, 1-3, 3-1, 1-4, 4-1, 1-5, 5-1, 1-6, 6-1, 2-3, 3-2, 2-4, 4-2, 2-5, 5-2, 2-6, 6-2, 3-4, 4-3,
3-5, 5-3, 3-6, 6-3, 4-5, 5-4, 4-6, 6-4, 5-6, & 6-5.
So although there are only 6 numbers you are up against a 29/1 chance.
The more runners in the race, the more you are up against it:
8 runners = 56 possible forecasts = a 55/1 chance
12 runners = 132 possible forecasts = a 131/1 chance
16 runners = 240 possible forecasts = a 239/1 chance
20 runners = 380 possible forecasts = a 379/1 chance, etc.
To calculate the number of possible forecasts in a race, take the number of runners and multiply
the number of doubles in that number by 2. A 6 runner race would give 15 doubles in 6 selections,
so it's 15 x 2 = 30. As each double e.g. 1-2 could finish either way round, 1-2 or 2-1
2. Forecast Doubles
A bookies delight! A £1 straight forecast double 1-2 in two 6 runner races has a ghastly 899/1
chance of being correct. This is because we have already established that in a 6 runner race there
are 30 possible forecasts, so in 2 races there 30 possible forecast outcomes in each race, so the odds
of a succesful double are 30 x 30 = 900, which is 899/1.
The 1-2 and 1-2 £1 double is just one of those 900 possible outcomes.
Obviously the more runners in each race then the higher the odds against having a correct
double.
3. Forecast Trebles
We have established above that there are 30 possible forecast outcomes in a 6 runner race.
Therefore a £1 straight forecast treble 1-2 in three 6 runner races has a nightmarish 26,999/1
chance of being correct. This represents 30 x 30 x 30 = 27,000 possible forecast treble outcomes.

4. Tricasts
Another frightening bet! It's difficult to pick a winner, a forecast means you also have to find the second
why make it even harder and go for the third as well? In a 6 runner race there 120 possible tricast outcomes.
This is because in 6 selections there are a possible 20 trebles but each treble can finish in 6 different ways.
For example just one of the trebles,
1-2-3 can finish as either 1-2-3, 1-3-2, 2-1-3, 2-3-1, 3-1-2 or 3-2-1 to make 6 possible tricast outcomes.
Therefore the number of possible Tricasts in a race is the number of trebles in selections/runners
multiplied by 6
Therefore a £1 Tricast 1-2-3 in a 6 runner race has a 119/1 chance of being correct.
5. Combination Tricasts
A £1 Combination Tricast 1-2-3 costs £6 as you are placing separate bets on the six possible tricasts within
those selections, 1-2-3 can finish as either 1-2-3, 1-3-2, 2-1-3, 2-3-1, 3-1-2 or 3-2-1 as detailed above.
Therefore a £1 Tricast 1-2-3 in a 6 runner race has a 19/1 chance of being correct. This represents the
120 possible outcomes divided by the six covered.
