I have a question that relates to this question about Venn diagrams. Has anyone shown that all Venn diagrams can (theoretically) be constructed?
Are both the Venn diagram's (i and ii) showing dependent properties (showing that A and B are dependent on one another), I am told that the quartered one is independent (Venn diagram i), however I do not see any difference between the 2 diagram's. Surely P(A|B) (probability of B given A), will co...
I am confused about creating a Venn diagram from the question below from one of the past papers as there is a negative number involved. Is this possible in Venn diagrams? A survey of students in a lecture revealed that a total of $15$ played rugby, $30$ played football and $35$ played cricket. $...
I'm hoping someone can explain how I go about drawing up venn diagrams in my discrete structures class. The book this class uses doesn't explain much at all, and gives only two examples.. My homework asks me to: Use Venn diagrams to determine whether each of the following is true or false: ...
How to show the following sets by Venn diagrams? Case 1: $$A=\{1,2,B\},B =\{3,4\}$$ Case 2: $$A=\{1,2,3,4\}, B=\{3,4\}$$
I want to know how to draw a Venn Diagram with the given information below.. There are 30 students: 16 are girls; There are 7 girls and 6 boys who have blue eyes. A student is randomly chosen to be class monitor. Draw a Venn Diagram to represent this information. Progres...
I was hoping someone could explain how these sets map out on the venn diagram. Mainly, i am confused on what the Triangle means in terms of the venn diagram. (The Triangle represents: The symmetric difference between the two sets) Is there a proof in which i can replace the triangle into unions ...
In a group of students, 30% play only cricket, 20% play only football and 10% play only basketball. 20% of the students play both football and cricket, 15% play both basketball and cricket, 10% play both football and basketball. 15 students play no games, while 5% of the students play all three g...
On this site it is common to see questions where OP asks if their approach or their solution to a problem is correct. Often, people answer these questions by providing their own entirely different proof. Example 1 Example 2. My opinion is that these answers do not address the question, and they ...
