assuming you only draw from the base deck
- Probability that you draw 0 clock is of 0.8333333333333334
- Probability that you draw 1 clock is of 7.5
- Probability that you draw 2 clock is of 12.5
- Probability that you draw 3 clock is of 20.833333333333332
- Probability that you draw 4 clock is of 22.5
- Probability that you draw 5 clock is of 17.5
- Probability that you draw 6 clock is of 12.5
- Probability that you draw 7 clock is of 4.166666666666667
- Probability that you draw 8 clock is of 1.6666666666666667
basicaly clock works best against 3,4 and 5,thus giving you odds of at least 60% when these 3 numbers are present,that increase to 72% if 2 is present too and tops at 85% when you add 6 to the mix,of course this also assume this is your first draw as your odds change when you eliminate 3 cards and have to draw from a pool of 7 possible card's
just know that there are 2 cards with 3 clocks (which is why it's impossible to draw 9 clock) 3 with 0 clock,2 with 2 clock and 3 card with 1 clock,so eliminating the card with 3 clock gives you better odd for lower numbers and eliminating card with no clock gives you better odds at higher numbers
EDIT: counting drawing 2 base card and 1 blue card
- Probability that you draw 0 clock is of 4.0
- Probability that you draw 1 clock is of 12.0
- Probability that you draw 2 clock is of 14.666666666666666
- Probability that you draw 3 clock is of 24.0
- Probability that you draw 4 clock is of 17.333333333333332
- Probability that you draw 5 clock is of 16.0
- Probability that you draw 6 clock is of 7.555555555555555
- Probability that you draw 7 clock is of 3.5555555555555554
- Probability that you draw 8 clock is of 0.8888888888888888
expansion set has 4 card with 2 clock and 6 card with 0 clock thus making the odd of drawing lower number higher although 3 and 4 are still the most probable one
