© 2015 American Physical Society. We present the final combination of CDF and D0 measurements of cross sections for single-top-quark production in proton-antiproton collisions at a center-of-mass energy of 1.96 TeV. The data correspond to total integrated luminosities of up to 9.7fb-1 per experiment. The t-channel cross section is measured to be σt=2.25-0.31+0.29pb. We also present the combinations of the two-dimensional measurements of the s- vs t-channel cross section. In addition, we give the combination of the s+t channel cross section measurement resulting in σs+t=3.30-0.40+0.52pb, without assuming the standard model value for the ratio σs/σt. The resulting value of the magnitude of the top-to-bottom quark coupling is |Vtb|=1.02-0.05+0.06, corresponding to |Vtb|>0.92 at the 95% C.L.
