We study two-component growth that mixes random deposition (RD) with a
correlated growth process that occurs with probability p. We find that these
composite systems are in the universality class of the correlated growth
process. For RD blends with either Edwards-Wilkinson of Kardar-Parisi-Zhang
processes, we identify a nonuniversal parameter in the universal scaling in p.Comment: 4 pages, 6 figures, 11 references; under revie
