. [8] A gambler suspects a six sided die is "loaded" meaning the center of mass of the die is not in the center but toward one face, thus shifting the probability of each face from 1/6 each to something else. In the course of 600 trials, she observes (122 "aces", 103 "twos.98 "threes 95 "fours", 105 "fives" and 77 sixes". On a die, the even and odd spots are on opposite sides so one way we could look at...
