We study the problem of cupping with random sets.
Nies has shown that
every random set below the halting problem has the strong random anticupping property via
a promptly simple anticupping witness. We show that every set below the halting problem (not necessarily random) has
the random anticupping property via a promptly simple anticupping
witness. Moreover, we prove the following stronger statement: for every
noncomputable Y below the halting problem
there exists a promptly simple A such that if the join of it with a random is above Y then the random set is above
A.
