Rolling a 5 on a fair number cube
1/6
To determine the probability of rolling a 5 on a fair number cube, you need to know the total number of possible outcomes and the number of favorable outcomes.
A fair number cube has six faces, numbered 1 to 6. So, the total number of possible outcomes is 6.
Since only one face on the cube is labeled 5, there is only one favorable outcome, which is rolling a 5.
To calculate the probability, divide the number of favorable outcomes by the total number of possible outcomes:
Probability = Number of Favorable Outcomes / Number of Possible Outcomes
In this case:
Probability of rolling a 5 = 1/6
So, the probability of rolling a 5 on a fair number cube is 1/6 or approximately 0.167.
