An interesting integral originally obtained by Tefera (“A multiple integral evaluation inspired by the multi-WZ method,” Electron. J. Combin., 1999, #N2) via the WZ method is proved using calculus and basic probability. General recursions for a class of such integrals are derived and associated combinatorial identities are mentioned. 1 Background The integral in question reads
