Abstract The probabilistic polynomial-time hierarchy (BPH) is the hierarchy generated by applying the BP-operator to the Meyer-Stockmeyer polynomial-time hierarchy (PH), where the BP-operator is the natural generalization of the probabilistic complexity class BPP. The similarity and difference between the two hierarchies BPH and PH is investigated. Oracles $\textit{A}$ and $\textit{B}$ are constructed such that both $PH(\textit{A})$ and $PH(\textit{B})$ are infinite while $BPH(\textit{A})$ is not equal to $PH(\textit{A})$ at any level and $BPH(\textit{B})$ is identical to $PH(\textit{B})$ at every level. Similar separating and collapsing results in the case that $PH(\textit{A})$ is finite having exactly $\textit{k}$ levels are also considered.
