Answer:
Pr(less\text{ than or equal to 4\rparen = }(2)/(3)\text{ \lparen option A\rparen}Step-by-step explanation:

Given:

A single die

To find:

the probability of rolling a number less than or equal to 4

The sample space in rolling a single die,= {1, 2, 3, 4, 5, 6}

The sample space for a number less than or equal to 4 = {1, 2, 3, 4}

To get the probability of rolling a number less than or equal to 4, we will apply the formula:


Pr(less\text{ than or equal to 4\rparen = }\frac{number\text{ of the sample sapace less than or equal to 4 }}{number\text{ of }Total\text{ sample space}}
\begin{gathered} number\text{ of sample space \le4 = 4} \\ number\text{ of total sample space = 6} \\ \\ Pr(less\text{ than or equal to 4\rparen = }(4)/(6) \\ \\ Pr(less\text{ than or equal to 4\rparen= }(2)/(3)\text{ \lparen option A\rparen} \end{gathered}
