I used the random option on the calculator, and then looked at the last digit and did a remainder division with 3.
example: calc showed up as 0.378 then took last digit "8" and did a remainder division with 3 to get "2" which for me means choose "B".
remainder division: 8/3 = 2 and 2/3 so the fraction is the "remainder" |
