Click For Summary
The discussion focuses on demonstrating the equivalence of the logical expressions p v (q ^ r) and (p v q) ^ (p v r) using a Venn diagram. Participants are encouraged to visualize the union and intersection of sets to understand the relationships between the variables. Additionally, it is highlighted that the expression p v (q ^ r) is not equivalent to (p v q) ^ r, prompting users to explore this distinction independently. The use of resources like Wolfram|Alpha is recommended for further exploration and clarification of these concepts. Understanding these logical relationships is essential for grasping foundational principles in set theory and logic.

can someone give me show me a venn diagram that will satisfy this statement
Venn diagram to show that the statement p v (q ^ r) is equivalent to (p v q) ^ (p v r) and show that this statement is not equivalent to (p v q) ^ r.

Here is the first half of your request:

Try to do the second one on your own-remember that the "vee" symbol represents UNION, and the "wedge" symbol represents INTERSECTION (when doing a Venn diagram):

Wolfram|Alpha (Wolfram|Alpha: Computational Knowledge Engine) is a great resource for budding mathematicians/students, and even just the interested lay-person.

First trick I learned this one a long time ago and have used it to entertain and amuse young kids. Ask your friend to write down a three-digit number without showing it to you. Then ask him or her to rearrange the digits to form a new three-digit number. After that, write whichever is the larger number above the other number, and then subtract the smaller from the larger, making sure that you don't see any of the numbers. Then ask the young "victim" to tell you any two of the digits of the...
