Original sentence: However, some assumptions about that undefined mechanism would be common sense when dealing with a practical experiment.In his 1973 paper The Well-Posed Problem, Jaynes argued that Bertrand's paradox arises because in the strict sense, the mechanism of the random experiment is not defined in Bertrand's question—in other words, the word "random" in 'suppose a chord is chosen at random' is ambiguous".In particular, we should expect the experiment to produce the same result no matter what the precise size and position of the circle is: it should be invariant under both scale and translation.This and other paradoxes of the classical interpretation of probability forced more rigorous approaches to probability, including the formulation of frequency probability
