When you rolla 6 sided die about what fraction of the time would you expect a factor of 20 to come up?
The factors of 20 are 1, 2, 4, 5, 10, and 20. We can take 10 and 20 off the list, because they're not on the six-sided dice. So, 4 out of 6 sides of the dice will give us a factor of 20. That means we can expect (if the dice is fair) to get a factor of 20 about 4/6 of the time. 4/6 simplified is 2/3.
