2d6 stuff page.

2 standard dice with 6 sides marked 1 through 6.

from sums, to tables, to collecting all the sums or the combinations.

rolling all 11 sums from 2d6.

the probability distribution. Used a Markov chain in Pari Gp calculator

below is the sheet for the distributions. below that are 2 photos of the distributions

1r. the average number of rolls of 2d6 to get at least 1 of every sum (coupon collecting with uneven probabilities) is 61.21738 from R code below. uses inclusion exclusion.
