I don’t have the setup (how many colors/items or counts) — can you share the list or diagram?
General answer you can use meanwhile:
- If selection is by picking uniformly at random from N items and color i appears c_i times, then color i has probability c_i / (sum_j c_j).
- So an individual color has probability 1/4 exactly when c_i = (total number of items)/4. In other words, its count must be one quarter of the total (so the total must be divisible by 4 if counts are integers).
Examples:
- If there are 4 colors and each appears once (total 4), each color has probability 1/4.
- If there are 12 items and a color appears 3 times, that color’s probability is 3/12 = 1/4.
If you meant something else (e.g., colors chosen uniformly from a palette of k colors, or probabilities given directly), paste the specifics and I’ll identify which color(s) give 1/4.
