Chapter 13.8, Problem 4GP

To determine

To calculate: Probability of rolling three $5s$ .

Answer to Problem 4GP

  $\frac{1}{216}$ is the Probability of rolling three $5s$ .

Explanation of Solution

Given information:

Three dice are rolled.

Total no of observation $=216$

No of possible outcomes (events) $=$ rolling three $5s$

Calculation:

As given information is,

Three dice are rolled.

So, Total no of observation $=216$

No of possible outcomes (events) $=$ rolling three $5s$

Now, divide the number of events by the number of possible outcomes

So,

  $\begin{array}{l}P\left(A\right)=\frac{S\left(A\right)}{S\left(P\right)}\\ =\frac{1}{216}\end{array}$

Therefore, Probability of rolling three $5s$ is $\frac{1}{216}$ .
