加法法則 A與B二事件之交集(Intersection)=A∩B 包括屬於A事件及B事件的結果 A與B二事件之聯集(Union)=A∪B 包括屬於A事件或B事件的結果 Venn Diagram P(A∪B)=P(A)+P(B)-P(A∩B) 例: 年齡 性別 20歲 非20歲 和 男 14 6 20 女 21 9 30 和 35 15 50 A:20歲 B:女性 P(A)=P(20...
mutually exclusive events exhaustive events venn diagram the below figure shows the venn diagram representation of collectively exhaustive events in comparison with exclusive events. go through the solved examples given below to understand the concept clearly. exhaustive events in probability with examples ...
In Figure 1, the Venn diagram of event A is shaded to represent it has occurred. Both events A and B occurring is represented in the region {eq}A\cap B {/eq}. In conditional probability, sample space became A and the event is {eq}A\cap B {/eq}. Therefore conditional probability ...

Exhaustive Events Venn DiagramNow, given below is a diagram showing the entire sample space of an experiment and Ai for i ∈ {1, 2, 3, 4, 5} are the possible events in S. Now, A1, A2, A3, A4, A5, are exhaustive events as one of them will definitely occur whenever the ...
The Venn diagram below shows the number of students who pass their mock exams in English and Maths. A student is chosen at random. Given that the chosen student passes Maths, find the probability that they did not pass English. Write out the basic probability. Show step Solve the problem...

AVenn diagramintersection shows events a and b happening together. 1. What is the Probability of A and B? The probability of A and B means that we want to knowthe probability of two events happening at the same time. There’s a couple of different formulas, depending on if you havedepe...

The symbol “∩” in a joint probability is referred to as an intersection.The probability of event X and event Y happening is the same thing as the point where X and Y intersect. Therefore, the joint probability is also called the intersection of two or more events. AVenn diagramis perh...
