Web1 Answer. Sorted by: 9. An algorithm being probabilistic means that it is allowed to "throw coins", and use the results of the coin throws in its computations. This is reasonable because a realistic adversary has access to certain pseudo-randomness sources (such as the C rand () function). Of course, a probabilistic algorithm is not required to ...
