Can you elaborate on c? Don't think it is correct...
I think I've found out:
pattern: For figure (f) even, there are more f gray triangles than white ones.
| 1 | 2 | 3 | 4 | 5 | 6 | 7 |
|---|---|---|---|---|---|---|
| 1 | 1 | 6 | 6 | 15 | 15 | 28 |
| 0 | 3 | 3 | 10 | 10 | 21 | 21 |
| +2 | +4 | +6 |
Total triangle = 62500
62500/2 = 31250
gray = 31375
white = 31125
50,2%

Great explanation

Correct :)

I seem to have missed the pattern of gray in the even figures, I've expanded the pattern and verified that it doesn't exist. Now I'm confused!
