I need help with generating random points and plot it onto my binary image (black and white).

Im trying to estimate an area using Monte Carlo Simulation from an image I've extracted using GeoChart. I've also changed the image to grayscale in order to get a white shade for my point of interest. But I seem to struggle on how to generate random points to be plotted onto my image.
