Probability of two non independent events
Webb13 juli 2024 · 1 It looks like you're misapplying the product rule for probabilities. The product rule is used for intersections of events whereas your question is about a union. You probably want to use P ( A ∪ B) = P ( A) + P ( B) − P ( A ∩ B). – tddevlin Jul 13, 2024 at 14:54 Sorry, typo from \cup instead of \cap! It's the intersection that I'm after, indeed. WebbConditions for Joint Probability One is that events X and Y must happen at the same time. Example: Throwing two dice simultaneously. The other is that events X and Y must be independent...
Probability of two non independent events

WebbIn this work, the non-homogeneous risk model is considered. In such a model, claims and inter-arrival times are independent but possibly non-identically distributed. The easily verifiable conditions are found such that the ultimate ruin probability of the model satisfies the exponential estimate exp { − ϱ u } for all values of the initial surplus u ⩾ 0 . WebbGiven two independent events, if the first event can yield one of n equiprobable outcomes and another has one of m equiprobable outcomes then there are mn equiprobable outcomes of the joint event. This means that if log 2 ( n ) bits are needed to encode the first value and log 2 ( m ) to encode the second, one needs log 2 ( mn ) = log 2 ( m ) + log …
