Magic 8-Ball--Icosahedral Based
 

Magic-8-Ball is Icosa(20)hedral Based

...."Ten of the possible answers are Positive, five are Negative, and five are Neutral. Using the coupon collector's problem in probability theory, it can be shown that it takes, on average, 72 outcomes of the Magic 8 Ball for all 20 of its answers to appear at least once."....


This 72 apparently has to do with icosa(20)hedrons 12 vertexes.

72 / 12 = 6

20 vertexial events have 190 lines-of-realtionship
..see n^2 minus n and then divide by 2.....

12^2 = 144

144 - 12 = 132

132 / 2 = 66
