$\dfrac{1}{2}$

Step-by-step explanation:

We know that on a standard number cube, there are total 6 outcomes.

The number written on a standard number cube = 1,2,3,4,5,6

Prime numbers = 2,3,5

Now, the theoretical probability of rolling a prime number on a standard number cube will be :_

$\dfrac{\text{Number of primes}}{\text{Total numbers}}\\\\=\dfrac{3}{6}=\dfrac{1}{2}$

Hence, the theoretical probability of rolling a prime number on a standard number cube = $\dfrac{1}{2}$
