Chapter 12.3, Problem 9PPS

To determine

To Find: The probability of given possibility.

Answer to Problem 9PPS

The probability is $\frac{1}{216}$ .

Explanation of Solution

Given information:

Total number of dice = 3

Two of the rolls are 4s.

Also, all rolls are same.

Total number of dice = 3

  $\begin{array}{l}\text{Total number of outcomes}=6*6*6\\ =216\end{array}$

Two of the rolls are 4s.

Also it is given that all of the rolls are same.

Hence, possible outcomes be

  $\left(4,4,4\right)$

Total number of possible outcomes is 1.

Hence ,

  $\text{Probability}=\frac{1}{216}$

Hence, required probability is $\frac{1}{216}$ .
