Question
Three identical dice are rolled. The probability that the same number will appear on each of them is:
- (a) 1/6
- (b) 1/12
- (c) 1/36
- (d) 1
Solution
The total number of outcomes when three dice are rolled is 666 = 216.
When we roll three identical dice, the number of favorable outcomes is 6 (i.e., (1,1,1), (2,2,2), (3,3,3), (4,4,4), (5,5,5), (6,6,6)).
So, the probability that the same number will appear on each of them is 6/216 = 1/36.
Therefore, the answer is (c) 1/36.
