In Mariokart DS, there are eight start up characters and additional 4 more unlockable characters. A photo will be taken of the top 3 racers. What is the probability that all top three racers will only be unlockable characters?

Assuming you had all of them (all 12) in a race like the Wii version it would be nearly 20%

If you had just 8 with the three unlock able characters in there like the DS it would be literally about 35% but of course its a game so its kind of configured on how to arrange everything lol
