What are the most likely modes of decay for ##\Omega ^{-}## into 2 hadrons?

##BR_{k}=\frac{\Gamma _{k}}{\Gamma}##

##\Gamma=\frac{\hbar}{\tau }##

##\Gamma _{k}=\Gamma _{if}=2\pi \rho|<\Psi _{i}|H_{Int}|\Psi _{f}>|^{2} (E_{f})##

I took a look at the Particle Data Group, and the most likely modes are ##\Omega ^{-}\rightarrow \Lambda K^{-}## (68%) and ##\Omega ^{-}\rightarrow\Xi ^{0}\pi ^{-}## (24%). I have some difficulties to understand which particle i should use to calculate the branching ratios. The exercise only says that it can decay in 2 hadrons, but it doesn't say which. How can i know this without looking at books as i did?
