What is the probability of getting a sum of 6 on 2 rolls of a fair die? Explain What is the probability nif the first roll is a 2? Explain

6 7 8 9 10 11 12
5 6 7 8 9 10 11
4 5 6 7 8 9 10
3 4 5 6 7 8 9
2 3 4 5 6 7 8
1 2 3 4 5 6 7
+ 1 2 3 4 5 6


With this schedule where the dice is marked red, and the black numbers are the sum of the two dices, you can count the probability. Ex; sum=6 there is five numbers with the sum of 6 out of 36 numbers. So the probability is 5/36
