To find the probability of rolling a 3 or a 4 on a number cube, you need to determine the number of favorable outcomes and divide it by the total number of possible outcomes.
In this case, Alicia can roll a 3 or a 4, which means there are two favorable outcomes: rolling a 3 or rolling a 4. The number cube has six sides, so there are six possible outcomes.
Therefore, the probability of Alicia rolling a 3 or a 4 is 2 out of 6, or simply 2/6. To simplify this fraction, you can divide both the numerator and denominator by their greatest common divisor, which in this case is 2.
So, the simplified probability is 1/3. This means that Alicia has a 1 in 3 chance of rolling a 3 or a 4.
