These branching fractions all scale with B( ${{\overline{\mathit b}}}$ $\rightarrow$ ${{\mathit B}_{{{s}}}^{0}}$ ).
The branching fraction B( ${{\mathit B}_{{{s}}}^{0}}$ $\rightarrow$ ${{\mathit D}_{{{s}}}^{-}}{{\mathit \ell}^{+}}{{\mathit \nu}_{{{{{\mathit \ell}}}}}}$ anything) is not a pure measurement since the measured product branching fraction B( ${{\overline{\mathit b}}}$ $\rightarrow$ ${{\mathit B}_{{{s}}}^{0}}$ ) ${\times }$ B( ${{\mathit B}_{{{s}}}^{0}}$ $\rightarrow$ ${{\mathit D}_{{{s}}}^{-}}{{\mathit \ell}^{+}}{{\mathit \nu}_{{{{{\mathit \ell}}}}}}$ anything) was used to determine B( ${{\overline{\mathit b}}}$ $\rightarrow$ ${{\mathit B}_{{{s}}}^{0}}$ ), as described in the note on ``${{\mathit B}^{0}}-{{\overline{\mathit B}}^{0}}$ Mixing''
For inclusive branching fractions, $\mathit e.g.,$ ${{\mathit B}}$ $\rightarrow$ ${{\mathit D}^{\pm}}$ anything, the values usually are multiplicities, not branching fractions. They can be greater than one.
