AB - The product branching ratio, f(b → Λ<inf>b</inf>) · BR(Λ<inf>b</inf> → ΛX), where Λ<inf>b</inf> denotes any weakly-decaying b-baryon, has been measured using the OPAL detector at LEP. Λ<inf>b</inf>'s are selected by the presence of energetic Λ particles in bottom events tagged by the presence of displaced secondary vertices. A fit to the momenta of the Λ particles separates signal from B meson and fragmentation backgrounds. The measured product branching ratio is f(b → Λ<inf>b</inf>) · BR(Λ<inf>b</inf> → ΛX) = (2.67) ± 0.38(stat)<sup>+0.67</sup><inf>-0.60</inf>(sys))%. Combined with a previous OPAL measurement, one obtains f(b → Λ<inf>b</inf>) · BR(Λ<inf>b</inf> → ΛX) = (3.50) ± 0.32(stat) ± 0.35(sys))%.
