Answer:

19/27

Explanation:

Each time that you roll a dice, there is a 1/3 chance you get a 5/6(assuming you have a fair dice). The probability of rolling that atleast once is the inverse of the probability of rolling a 1-4 each time. There is a
(2)/(3) chance each time you roll the dice. Thus raising this to the third power results in
(8)/(27). Since we are looking for the inverse probability, we can do:


1-(8)/(27) In order to get our final answer.
