Answer
The required solution of probability is, $0$
Work Step by Step
We know that when the die is rolled then the sample space of equally likely outcomes given below is $ S=\left\{ 1,2,3,4,5,6 \right\}$
As there are six outcomes in the sample space, thus, $ n\left( S \right)=6$
Also, the event of getting a number greater than 7 can be represented as $ E=\phi $
Since there is only one outcome in this event, therefore, $ n\left( E \right)=0$
Thus, the probability of obtaining a number greater than 4 is:
$\begin{align}
& P\left( E \right)=\frac{n\left( E \right)}{n\left( S \right)} \\
& =\frac{0}{6} \\
& =0
\end{align}$
