MHB Probability of Even # or Mult. of 3 from 1-10

Click For Summary
The discussion focuses on calculating the probability of selecting an even number or a multiple of 3 from the numbers 1 to 10. Even numbers in this range are 2, 4, 6, 8, and 10, while the multiples of 3 are 3, 6, and 9. The overlap between even numbers and multiples of 3 includes the number 6. Participants clarify that "multiply of 3" refers to multiples of 3, specifically 3, 6, and 9. The final probability is derived from the total favorable outcomes versus the total possible outcomes.

Thread 'Area of Overlapping Squares'

Here is a little puzzle from the book 100 Geometric Games by Pierre Berloquin. The side of a small square is one meter long and the side of a larger square one and a half meters long. One vertex of the large square is at the center of the small square. The side of the large square cuts two sides of the small square into one- third parts and two-thirds parts. What is the area where the squares overlap?
