The probability of possible values for the four angles of the CKM matr
ix are determined by finding the chi(2) values for each choice of angl
es fitting to ten standard experiments. The chi(2) isosurface plots ar
e first displayed in the space of three of the CKM angles showing the
dependence of the bounds on delta and greatly improving the lower boun
d on V-cb. The maximum likelihood chi(2) contour plot in the rho/eta p
lane shows the probability of each location for the vertex of the unit
arity triangle which controls CP-violating asymmetries in B-0 decays.
We find for m(t) = 150 GeV that at the 2 sigma level the signal for as
ymmetries measuring sin(2 beta) is at least sin(2 beta) greater than o
r equal to 0.25. At the 1 sigma level the signal is at least sin(2 bet
a) greater than or equal to 0.40, with the preferred range of sin(2 be
ta) = 0.6 +/- 0.2.
