When you rolla 6-sided die about what fraction of the time would you expect a factor of 20 to come up?

Answer 1

-14

Answer 2

Total possible outcomes of one cube = 6.

Factors of 20 that can show on the cube: 1, 2, 4, and 5 . . . . 4 of the 6 possibilities.

Probability of rolling a factor of 20 = 4/6 = 2/3 = 662/3 % .

That's the probability on each individual roll, and the fraction of success during

an infinite number of rolls. It doesn't tell you anything about what to expect on

any single roll, regardless of anything that came before. There's no such thing as

"my number is due".

Example: If none of the previous 10 rolls was successful, that doesn't tell you

anything about what to expect on the 11th one.

Answer 3

2/3 of the time.
