Select the number of wild dice to roll. If all dice roll a 1, a WILD EVENT occurs!

NOTES: This is designed to quickly and easily simulate a range of probability events while not needing the players to count individual dice.

Rough Probabilities per # of Dice rolled for a WILD DICE set (all ones come up) are:

1 x Dice: 1 out of 6 (16.67%)
2 x Dice: 1 out of 36 (2.78%)
3 x Dice: 1 out of 216 (0.46%)
4 x Dice: 1 out of 1296 (0.077%)
5 x Dice: 1 out of 7776 (0.013%)
6 x Dice: 1 out of 46,656
7 x Dice: 1 out of 279,936
8 x Dice: 1 out of 1,679,616
9 x Dice: 1 out of 10,077,696

This enables you to quickly simulate the probabilities of being pulled over for a truly random cargo/customs check by Spaceport Customs -- Galaxy Guide 7: Mos Eisley reveals on page 15 that the rate of inspections at Mos Eisley Spaceport is about 1 in 500; so if you wanted to simulate the chances of this happening to you, you'd throw three dice to get within that rough order of magnitude.

This concept enables the GM to quickly scale up or down the search probability as needed - perhaps there's a ISB bulletin that all Corellian-registered ships with a specific departure sector must be searched; but the port is so busy that they can only manage about 1/36 (two dice).
