In Reply to: Re: Het x het breeding. 0, 1, 2, 3 or 4 albinos from 4 eggs?? posted by Bob Garby on October 24, 2001 at 11:16:48:
0.75^(n-x) for n-x normal looking snakes
0.25^x for x albinos
n!/(x!*(n-x)!) for the number of possibilities.
example:
2 eggs, 1 albino
egg#1 or egg#2 could be the albino egg -> 2 possibilities.
2!/(1!*(2-1)!)=2/(1*1)= 2
: For a clutch of N eggs from a het albino to het albino breeding, the chance of producing X albino hatchlings can be calculated using this formula:
: P[X] = 0.75^(N-X) * 0.25^(X) * N! / [X! * (N-X)!]
