  String theory has no parameter except the string scale, so a dynamically
compactified solution to 4 dimensional spacetime should determine both the
Planck scale and the cosmological constant $\Lambda$. In the racetrack K\"ahler
uplift flux compactification model in Type IIB theory, where the string theory
landscape is generated by scanning over discrete values of all the flux
parameters, a statistical preference for an exponentially small $\Lambda$ is
found to be natural (arXiv:1305.0753). Within this framework and matching the
median $\Lambda$ value to the observed $\Lambda$, a mass scale ${\bf m}\simeq
100$ GeV naturally appears. We explain how the electroweak scale can be
identified with this mass scale.
