I was wondering if there are any FREE good alternatives to Sheldon Ross's Probability Models which are more succinct?
Are there any free online resources (websites/PDFs/course notes) which cover more or less the same material?
I am looking for a quick (review)/(filling of knowledge gaps) and therefore would appreciate brevity.
how about this one from Oliver Knill's page at Harvard: http://www.math.harvard.edu/~knill/teaching/math144_1994/probability.pdf
