From what I have figured out:
2876 quad births:6.5bil people births
thats about 1 : 2.3 mil odds that any given birth would be quads
50 ident. quads : 2876 total quads
1 : 57.5 that the quads will be identical
Ratio of quads to births times the ratio of identical quads to quad births would give identical quads to births (I think):
1 : 14.2mil
I hope this helps (and I have too much time on my hands as well)
