The Lambda(c)(+)-->pK(-)pi(+) yield has been measured in a sample of two-jet continuum events containing both a charm tag ("(D) over bar") as well as an antiproton (e(+)e(-) --> (D) over bar (p) over bar X), with the antiproton in the hemisphere opposite the (D) over bar (measurement of charge conjugate modes is implicit throughout). Under the hypothesis that such selection criteria tag e(+)e(-)-->(D) over bar (p) over bar Lambda(c)(+)X events, the Lambda(c)(+)-->pK(-)pi(+) branching fraction can be determined by measuring the pK(-)pi(+) yield in the same hemisphere as the antiprotons in our (D) over bar (p) over bar X sample. Three types of (D) over bar charm tags are used, pi(soft)(-) (from D*- --> (D) over bar(o) pi(soft)(-) electrons (from (D) over bar-->Xe- nu), and fully reconstructed (D) over bar(o) --> K+ pi(-) or D- -->K+ pi(-)pi(-) or D-s(-) --> phi pi(-). Combining our results obtained from the three independent charm tags, we obtain B(Lambda(c)(+) --> pK(-) pi(+)) = (5.0 +/- 0.5 +/- 1.2)%.
