It is not necessary for exhaustive events to be mutually exclusive. In other words, we can say that exhaustive events are of two types - mutually exclusive exhaustive events and exhaustive events that are not mutually exclusive. Let us now see theVenn diagramfor exhaustive events in a sample s...
Venn diagram for proof of Theorem 2.1. Many other fundamental results can also be obtained from the basic axioms of probability. A few simple ones are presented here. More will be developed later in this chapter and in subsequent chapters. As with Theorem 2.1, it might help the student to ...

So, the total possibility for a second die is 3. Probability ( First die is 4, Second die is odd outcome)=336=112Probability ( First die is 4, Second die is odd outcome)=336=112 This is how we use the possibility diagram to answer probability-related questions. It is very importan...
Step 3:Insert your answers into the formula: P(B|A) = P(A∩B) / P(A) = 0.2 / 0.4 = 0.5. The probability that a buyer bought bucket seats, given that they purchased an alarm system, is 50%. Venn diagram for 90 buyers, showing that 20 alarm buyers also purchased b...

A joint probability can be visually represented through a Venn diagram. Consider the joint probability of rolling two 6’s in a fair six-sided dice: Shown on theVenn diagramabove, the joint probability is where both circles overlap each other. It is called the “intersection of two events.”...
Under what conditions can two mutually exclusive events be independent? 14. a. What is a probability tree? b. What are the four rules for probability trees? 15. What is a joint probability table? 16. What is a Venn diagram? Problems Problems marked with an asterisk (*) are solved in ...
Example 6: using a Venn diagram 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 ...
