I think the reason that it feels counter-intuitive for us to think of any combination of bucks and does in a litter as being possible is that there is actually a higher probability of near-equal numbers of bucks and does than of having a litter of mainly bucks or mainly does (if we're going with 50/50--having never bred rabbits, I don't know what affects if there's a 50% chance of producing either sex). It's not enough of a difference that having mostly bucks or mostly does in a litter is really anything to be surprised or concerned about, though--it's just something that's kind of neat. (This would be the case for any animals that average 50% each sex born, or near 50%.) If the percentage is something other than 50%, it just means that some options are more likely than others.
Earlier, I listed all the ratios of does to bucks that are possible in a litter with 9 kits, but some of those actually have a higher probability of occurring than others, just because there's more ways of getting, say, a litter with 4 bucks and 5 does (for example: First kit: buck; second: doe; third: buck; fourth: doe; fifth: buck; sixth: doe; seventh: buck; eighth: doe; ninth: doe), than of getting all does (there is only one way to get that.) If you want to picture how many more ways there are to get a mostly-evenly-divided litter than one that is mostly bucks or mostly does, I've put together a little chart of the different combinations possible in a 5-kit litter (because a 9-kit litter would be way too much to draw out--but it's the same concept with a larger litter). I've represented doelings with blue dots and bucklings with red dots.
(And of course, if you're not interested in picturing how that would look, don't mind Miss Math Person here I just like charting out statistics and probabilities and stuff)
So, all in all, any of those rows of dots are equally likely in a litter (if there's a 50% chance of either sex being produced). Which means that it's just as likely that you'll get 1st: buck, 2nd: doe, 3rd: doe, 4th: doe, 5th: buck, as it is that they will all be does. Even though there are more ways to get 2 bucks and 3 does than to get all does.
(Here's hoping I haven't gone and made it more confusing... :roll: )
