Use the complement to find each probability.
What is the probability of not rolling a 5 on a standard number cube?
My answer is 1/6 since there are 6 faces
Is this correct and if not can you explain on how to do this?
Thank you
I'm not sure. But the probability of not rolling a 5 is 5/6
What is the probability of NOT rolling a 5 on a standard number cube?
Think about it. If you rolled the number cube, you'd probably NOT get a 5.
The probability of rolling a 5 is 1/6 1 out of 6.
They are saying to figure out the complement. What do they mean by this?
Hello Ms. Sue. I looked at website now that gave me more of an explanation. Complement is the opposite so 5 out of 6 would be the answer.

Your answer is not correct. To find the probability of not rolling a 5 on a standard number cube, you need to calculate the complement of rolling a 5.
The complement of an event is the opposite of that event. In this case, the complement of rolling a 5 is not rolling a 5.
A standard number cube has six faces, numbered from 1 to 6. Out of these six outcomes, only one of them is a 5. So, the probability of rolling a 5 is 1/6.
To find the probability of not rolling a 5, you subtract the probability of rolling a 5 from 1, which is the total probability.
Total probability = 1
Probability of rolling a 5 = 1/6
Probability of not rolling a 5 = 1 - 1/6 = 5/6
Therefore, the correct answer is 5/6.
