If A=2, B=3, then what does (A) + (B)=

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 :_

Hence, the theoretical probability of rolling a prime number on a standard number cube =
