The chance of rolling a four with a single dice in three attempts is 1/18

Step-by-step explanation:

The reason for this is there are six sides on a dice. Therefore if you were rolling it one time you'd have a one-in-six chance since there is one four in the six sides. To get the chance for three roles you'd just multiply your probability for one role by the number of roles and it would give you 1/18.

I hope this helps!:)
