In this paper, a virtual element method for the stochastic Stokes equations driven by an additive white noise is proposed and analyzed. The velocity is approximated by the lowest-order virtual element which is originally designed for the Poisson equation and the projection is also taken as the one originally for the Poisson equation, while the pressure is approximated by the traditional discontinuous piecewise constant element. For stable approximations, we adopt a stabilization associating with the pressure jumps. We show the inf-sup condition and derive the stability. We moreover obtain the error estimates in various norms and the estimates of the expectation of the errors through the Green function. Numerical results on polygonal mesh are presented to illustrate the performance of the proposed method and the theoretical results obtained.
