Geometry

Question Analysis
This problem combines area calculation with geometric probability.This question involves geometric probability with overlapping regions.
The main focus is finding the ratio of the fountain's area to the garden's area.

Key Concept Explanation
Probability = Area of desired region / Total possible area
For circles: Area = r²
For rectangles: Area = length × width

Step-by-Step Solution
Garden area = 20 × 30 = 600 m²
Fountain area = (5)² = 25
