Based on the fact that two dice were rolled together, the probability of getting a sum of 7 is 16.7%.
What is the probability of getting a sum of 7?
The first step is the find the possible combinations that will add up to seven.
These are:
- (1, 6)
- (2, 5)
- (3, 4)
- (4, 3)
- (5, 2)
- (6, 1)
There are six combinations that could yield a sum of 7 when both die are rolled together.
The total combinations when two dice are rolled is:
= Number of sides on one cube x Number of sides on other cube
= 6 x 6
= 36
The probability of rolling a combination with a sum of 7 is:
= Number of combinations that add up to 7 / Total number of combinations
Solving gives:
= 6 / 36
= 1 / 6
= 16.7%
In conclusion, there is a 16.7% probability of rolling a sum of 7.
