We attempt an estimate of vertical bar V/sub ub//V/sub cb/vertical bar from the recent ARGUS observation of B/sup + -/ ..-->.. p anti p..pi../sup + -/ and B/sup 0/ ..-->.. p anti p..pi../sup +/..pi../sup -/ by studying general processes of the type B ..-->.. N anti N + n..pi.. (n greater than or equal to 0). The main ingredients of the analysis are the pion multiplicity distribution and a few models for the isospin structure of the final state. It is concluded quite generally that vertical bar V/sub ub//V/sub cb/vertical bar = 0.25 +- 0.10 and vertical bar V/sub ub//V/sub cb/vertical bar greater than or equal to 0.08. The ratio may become lower only in the event that both the relevant experimental and theoretical quantities obtain the extreme values considered in our study. We also discuss briefly a possible realization of a ..delta..I = 1/2 rule in these processes.
