probabilistic combinatorics algebra e
It is sometimes said that probabilistic combinatorics uses the fact that whatever happens with probability greater than 



0


{\displaystyle 0}

 must happen sometimes; one may say with equal justice that many applications of probabilistic number theory hinge on the fact that whatever is unusual must be rare. If certain algebraic objects (say, rational or integer solutions to certain equations) can be shown to be in the tail of certain sensibly defined distributions, it follows that there must be few of them; this is a very concrete non-probabilistic statement following from a probabilistic one.
