If you do every combination of .25 and .75 that you can, then you won't get all the way to 100%, only 96%.
    I explained it more here: http://ball-pythons.net/forums/showt...ble-recessives

    You do have a 10.5% chance at getting ONE albino when looking at only one egg, so that's a 4*10.5%=42% (there are 4 different ways of getting one albino out of 4), but you also have a 6*(.75*.75*.25*.25)= 21% chance at getting two (there are 6 ways of getting two), and a 4*(.253*.75)=4.68% chance at getting 3 (there are four ways to get 3), and a .254=0.4% chance at getting 4 in a 4 egg clutch. Add those up and you get 68% chance, and if you find the chance you don't get one (.754), you get 31.6% chance... which when you add those two together, you get 100% chance of all outcomes. I go into that in that thread I created in response to this
    1.0 Pied 0.1 Pied het Albino
    1.0 Albino het Pied 0.1 Hog Island Boa
    0.1 het Albino, 50% het Pied 0.1 Black lab
