Webb14 jan. 2024 · The three axioms set an upper bound for the probability of any event. We denote the complement of the event E by EC. From set theory, E and EC have an empty intersection and are mutually exclusive. Furthermore E U EC = S, the entire sample space. These facts, combined with the axioms give us: 1 = P ( S) = P ( E U EC) = P ( E) + P ( EC) . Webb22 nov. 2024 · In 200 toss, the probability of having exactly 100 heads is around 5,6%. It is not that much. And if you train yourself, you can add a biais to the experiment. If I toss a coin and catch it, I can get about 90% of heads (same coin, approximately same force). – Alain Remillard Nov 22, 2024 at 18:08 2
