Answer:
The probability is 0.1944
Step-by-step explanation:
Since we are rolling two dice, the number of possible results is 36
for us to get a sum of seven, these are the possible results;
1 and 6
6 and 1
2 and 5
5 and 2
3 and 4
4 and 3
The probability of rolling a sum of 7 is 6/36
For a sum of 12, we only have one possible result and that is 6,6
So the probability here is 1/36
If we have or in probability, we add up the individual probabilities
So, our probability here will be;
1/36 + 6/36
= 7/36 = 0.1944
