Imperious Surfaces

So I'm fairly new to GIS. I had a raster of impervious vs pervious surfaces and I converted it to polygons. Even though the brown is all the same color, the individual polygons have a grid code value of either 0 or 1 (impervious or pervious surface). I was wondering if it is possible to find the ratio/percentage of 0 to 1s within my watershed (the highlighted blue line). Any feedback would be much appreciated. Thanks.
