We have numerically computed survival probabilities of solar neutrinos interacting with matter via MSW mechanism in the full three generation formalism with Δm223=2.2× 10-3 eV2. For θ13 \lesssim 30∘, we confirm the two regions found in the two generation case, (1) with the most likelyhood, small sin2(2θ12) ∼ 0.006, (2) with less likelyhood, large sin2(2θ12) \gtrsim 0.5. For θ13\gtrsim 30∘, we find an additional region, (3) with even less likelyhood, 10-5 < Δm212< 10-4 eV2 and/or 10-4 < sin2(2θ12) < 0.5. Assuming that the case (1) is valid, we predict that θ13 ≃ 15^∘.
