Prediction for the number of unsuccessful rolls is 15.
<h2>
Step-by-step explanation:</h2>
There is 
chance of rolling number 6 on the cube. If we want to find out what is the prediction for rolling number 6 in 18 rolls, we need to multiply 
which is 3. So if we roll a cube 18 times, we will probably got number 6 three times. When we subtract 3 from 18 (18-3), we get 15. That is the answer to your question.
