What is the probability of rolling a 1 or a 5 with a 6 sided number dice?
Either/or add probabilities.
2 choices out of 6 = 2/6 = 1/3
There is my idea above.
Any ideas?
Oh thank you!
To determine the probability of rolling a 1 or a 5 with a 6-sided number dice, we need to first find the total number of favorable outcomes and divide it by the total number of possible outcomes.
In this case, the favorable outcomes are rolling a 1 or a 5. We have two ways to obtain a 1 (rolling a 1) and one way to obtain a 5 (rolling a 5). So, the total number of favorable outcomes is 2 (for rolling a 1) + 1 (for rolling a 5) = 3.
On the other hand, the total number of possible outcomes when rolling a 6-sided die is 6 (as it has six sides numbered from 1 to 6).
Therefore, the probability of rolling a 1 or a 5 is given by dividing the favorable outcomes by the total possible outcomes:
Probability = Favorable Outcomes / Total Possible Outcomes
Probability = 3 / 6
Simplifying, the probability is 1/2 or 0.5.
So, the probability of rolling a 1 or a 5 with a 6-sided number dice is 1/2 or 0.5.
