Mario Kart Wii item probability distributions

The following tables are used in Mario Kart Wii to determine the probability of receiving an item when an Item Box is opened. Like in Mario Kart DS, only the tables for the default case are stored in the game's files; in Mario Kart Wii, it is known as the "Balanced" case. The probability is coded as percentage multiplied by two. The distributions are presented in the order used in the code.
