In a dice game, what is the probability of rolling a factor of 6 on a six-sided die?
Possible Answers:
Correct answer:
Explanation:
To find the probability of an event, we will use the following formula:
Now, given the event of rolling a factor of 6 on a dice, we can calculate the following:
because there are 4 factors of 6 on a dice:
- 1
- 2
- 3
- 6
Now, we can calculate the following:
because there are 6 possible outcomes we could potentially get when rolling a dice:
- 1
- 2
- 3
- 4
- 5
- 6
Knowing this, we can substitute into the formula. We get
Therefore, the probability of rolling a factor of 6 on a dice is .
