Frolov" ], "categories": [ "math.PR" ], "abstract": "We derive new upper and lower bounds for probabilities that $r$ or at least $r$ from $n$ events occur. These bounds can turn to equalities. The method is discussed as well. It works for measurable space and measures with sign, too. We also discuss variants of the results for conditional probability of above events given $\\sigma$-field. Taking expectations from both parts of inequalities for conditional probabilities can yield better bounds for unconditional ones.", "revisions": [ { "version": "v1", "updated": "2020-08-08T20:28:30.000Z" } ], "analyses": { "subjects": [ "60E15", "60F15" ], "keywords": [ "lower bounds", "conditional probability", "combinations", "yield better bounds", "events occur" ], "note": { "typesetting": "TeX", "pages": 0, "language": "en", "license": "arXiv", "status": "editable" } } }
