random binary output based on probability

Discussion created by wookie on Jun 20, 2011
I have a raster of probability (0 to 1), and I have a point layer. I would like the point layer to show either 0 or 1 based on the probability of the raster layer, but with some variation from run to run. Can you do this with a random function multiplied by the raster somehow?

Thanks for any help.
