What Roblox requires

From Roblox's paid random items guidelines: show every possible outcome and its odds as a percentage before purchase; the percentages must sum to exactly 100%; long decimals may be rounded to four or more decimal places below the first non-zero digit, with the disclaimer "Probabilities are rounded; total of displayed individual probabilities may not equal 100%."; pity systems and luck boosts must be explained numerically, and boosted odds shown while active; if odds don't fit on screen, use a clearly labelled "Info" or "Details" button (a bare (i) icon is not enough). This page reads "four places below the first non-zero digit" as: 12.3456% → 12.346%, 0.0123% → 0.012300%. If in doubt, add extra decimal places. This tool is a helper, not legal advice; the policy page is the source of truth.
