Problem Statement

Let ABCABC be a triangle. Choose points AA', BB' and CC' independently on side segments BCBC, CACA and ABAB respectively with a uniform distribution. For a point ZZ in the plane, let p(Z)p(Z) denote the probability that ZZ is contained in the triangle enclosed by lines AAAA', BBBB' and CCCC'. For which interior point ZZ in triangle ABCABC is p(Z)p(Z) maximised?
