Three 6 faced dice are thrown together. The probability that all the three show the same number on them is _____ ?

Explanation:

It all 3 numbers have to be same basically we want triplets. 111, 222, 333, 444, 555 and 666. Those are six in number. Further the three dice can fall in 6 * 6 * 6 = 216 ways.

Hence the probability is 6/216 = 1/36
