Quizplus · Accepted Answer

The odds of side 3 turning up are calculated by comparing the number of times side 3 appears to the number of times it does not. Side 3 appears 28 times, so it does not appear 72 times (100 - 28). The odds are therefore 28 to 72, which simplifies to 7 to 18 when both numbers are divided by 4.
