I ran across this on another forum and we're running in circles trying to figure it out:
Scenario: I have two lines that intersect, both are 8 inches long. (Assume "8 points on the line" ignore the zero->one) The lines intersect at an inch mark.
There are 4 dots distributed along line A, randomly, but always fall on an inch mark (not in between). So at any given inch mark, there is a 50% chance of finding a dot.
There are 2 dot distributed along line B, randomly, but always fall on an inch mark. So at any given inch mark on line B, there is a 25% chance of finding a dot.
How do I calculate the odds of finding a dot where the lines interesect?
Example of the lines:
