Find P(rolling 1 or 5) with one number cube.
To find the probability of rolling a 1 or a 5 on a number cube (6-sided die), we first need to determine the total number of possible outcomes. Since there are 6 faces on a standard number cube, the total number of outcomes is 6.
Next, we need to determine the number of favorable outcomes, which in this case is rolling a 1 or a 5. There are 2 favorable outcomes, rolling a 1 or a 5.
Therefore, the probability of rolling a 1 or a 5 on a number cube is 2/6, which simplifies to 1/3. Thus, the probability of rolling a 1 or a 5 on a number cube is 1/3.
