We address the issue of whether quasifree single-nucleon knockout measurements carry sufficient information about the nuclear interior. To this end, we present comparisons of the reaction probability densities for A(e,e{sup '}p) and A(p,2p) in quasifree kinematics for the target nuclei {sup 4}He, {sup 12}C, {sup 56}Fe, and {sup 208}Pb. We adopt a comprehensive framework based on the impulse approximation and on a relativized extension of Glauber multiple-scattering reaction theory in which the medium effects related to short-range correlations (SRCs) are implemented. It is demonstrated that SRCs weaken the effect of attenuation. For light target nuclei, both the quasifree (p,2p) and (e,e{sup '}p) can probe average densities of the same order as nuclear saturation density {rho}{sub 0}. For heavy nuclei such as {sup 208}Pb, the probed average densities are smaller than 0.1{rho}{sub 0} and the (e,e{sup '}p) reaction is far more efficient in probing the bulk regions than (p,2p).
