What type of random is used for colonies/platinum and shelters

[Vivames]

Hi, I wondered how the chance is determined if I set colonies/platinum and shelters to random. Is it a dice roll or is it as suggested in the dominion strategy wiki a weighed chance based on the amount of prosperity and dark ages cards?

The latter. First the rest of the kingdom is generated, then a random card is picked from it. If it's from prosperity, use colony/platinum. Then pick a random card again. If it's from Dark Ages, use shelters.
