No one knows how many are "enough". One might be plenty, but 100 might not be enough. If you knew the circumstances ahead of time you could make a reasonable guess on how many might be enough - but that's something we don't know ahead of time (or at least rarely know it).
Think of it as putting gas in your car. If you don't know where you're going how much is enough? If you find you've reached your destination after 10 miles then a gallon was likely enough. If it turns out your destination was 1000 miles away then a full tank probably wasn't enough.
I try to base my ammo count on where I'm going. If I'm walking out to the mailbox a 2 shot derringer would probably be more than adequate (where I live), but if I'm going to Walmart a hundred rounds may not be enough (these days!)! :-)
