Then we need to look at the probability that the two dice will roll a number that matches.
Then we evaluate the probability of the rolls being this match outcome for each d12 case. Then sum.
d12 | d12 prob | 2xd6's match prob | prob of this match |
1 | 1/12 | 0/36 | 0/432 |
2 | 1/12 | 1/36 | 1/432 |
3 | 1/12 | 2/36 | 2/432 |
4 | 1/12 | 3/36 | 3/432 |
5 | 1/12 | 4/36 | 4/432 |
6 | 1/12 | 5/36 | 5/432 |
7 | 1/12 | 6/36 | 6/432 |
8 | 1/12 | 5/36 | 5/432 |
9 | 1/12 | 4/36 | 4/432 |
10 | 1/12 | 3/36 | 3/432 |
11 | 1/12 | 2/36 | 2/432 |
12 | 1/12 | 1/36 | 1/432 |
Probability of match | 36/432 |
The probability of a match is 8.333% - also 1/12
I'll say it's 1/13, or 1 in 13 tries.
I sent you ! Thanks !
