The capture cross sections and fission fragment angular distributions were measured for the reaction of $^{50}\mathrm{Ti}$ with $^{208}\mathrm{Pb}$ at center of mass projectile energies (${E}_{\mathrm{c}.\mathrm{m}.}$) of 183.7, 186.2, 190.2, 194.2, and 202.3 MeV (${E}^{*}=14.2$, 16.6, 20.6, 24.7, and 32.7 MeV). From fitting the backward angle fragment angular distributions, the cross sections for quasifission and fusion-fission and ${P}_{\mathrm{CN}}$, the probability that the colliding nuclei go from the contact configuration to inside the fission saddle point, were deduced. These quantities, along with the known values of the evaporation residue production cross sections for this reaction, were used to deduce values of the survival probabilities, ${W}_{\mathrm{sur}}$, for this reaction as a function of excitation energy. The deduced values of ${P}_{\mathrm{CN}}$ and ${W}_{\mathrm{sur}}$ and their dependence on excitation energy differ from some current theoretical predictions of these quantities.
