A) 0.6 
E) none of the above

Quizplus · Accepted Answer

The probability of rolling an even number on a fair die is 1/2. 
The probability of rolling an even number three times in a row is (1/2) x (1/2) x (1/2) = 1/8. 
Therefore, the probability of rolling an even number each time in three rolls is (1/8) = 0.125 or 12.5%. 
The only option that matches this value is C.
