The ratios of inclusive electron scattering cross sections of {sup 4}He, {sup 12}C, and {sup 56}Fe to {sup 3}He have been measured at 1<x{sub B}<3. At Q{sup 2}>1.4 GeV{sup 2}, the ratios exhibit two separate plateaus, at 1.5<x{sub B}<2 and at x{sub B}>2.25. This pattern is predicted by models that include 2- and 3-nucleon short-range correlations (SRC). Relative to A=3, the per-nucleon probabilities of 3-nucleon SRC are 2.3, 3.1, and 4.4 times larger for A=4, 12, and 56. This is the first measurement of 3-nucleon SRC probabilities in nuclei.
