@Nupur Goyal: "not work" is not a usefulö description of the problem. Please do not let the readers guess, what the problem is.
Grey scale images do not have 3 dimensions. So "(:,:,1) to (:,:,3)" means, that you do not have a grey scale image.
Alex's answer contains all you need: im==1 to get the indices and sum() to calculate the sum. Please try to combine these command until you get, what you want.
