1.	Three identical dice are rolled. The probability that same number appears on them, isA. `(1)/(6)`B. `(1)/(36)`C. `(1)/(18)`D. `(3)/(28)`
Answer» Correct Answer - B The total number of elementary events associated to the random experiment of throwing three dice simultaneously is `6^(3)`. Same number appears on three dice in `.^(6)C_(1)` ways. `therefore` Probability of getting the same number `=(.^(6)C_(1))/(6^(3))=(1)/(6^(2))=(1)/(36)`
