Starting from right to left is the possible outcome (2 to 12), the number of possible combinations, which will result in this outcome, and finally the odds of rolling this number.

Outcome Combinations of Dice Odds (%)
#2 1-1 35 to 1 (2.78)
#3 1-2, 2-1 17 to 1 (5.56)
#4 1-3, 2-2, 3-1 11 to 1 (8.83)
#5 1-4, 2-3, 3-2, 4-1 8 to 1 (11.11)
#6 1-5, 2-4, 3-3, 4-2, 5-1 31 to 5 (13.89)
#7 1-6, 2-5, 3-4, 4-3, 5-2, 6-1 5 to 1 (16.67)
#8 2-6, 3-5, 4-4, 5-3, 6-2 31 to 5 (13.89)
#9 3-6, 4-5, 5-4, 6-3 8 to 1 (11.11)
#10 4-6, 5-5, 6-4 11 to 1 (8.83)
#11 5-6, 6-5 17 to 1 (5.56)
#12 6-6 35 to 1 (2.78) 6

As you can see, the most frequent outcome is 7. Six of every thirty-six outcomes give you 7. Therefore the chances of rolling a seven are 6/36 (5 to 1 or 16.67%). The rarest outcomes are 2 and 12. There is only one possible combination for each of these, i.e. 1+1=2 and 6+6=12. One out of thirty-six potential outcomes means the chances of rolling either of these numbers is 1/36 (35 to 1).

In order to calculate the odds of winning the come-out roll we must consider the chances of rolling either a 7 or an 11. The number of potential combinations for this are 6 and 2. This means that your chances of rolling either a 7 or an 11 are 8/36.

Naturally you will wonder at the chances of losing the come-out roll. Well, if we add the chances of rolling a 2 (1/36), a 3 (2/36), or a 12 (1/36), we have a 4/36 (1 + 2 + 1 = 4) chance of losing. Therefore, the chances of winning the come-out roll are exactly double that of losing it.

In total, the chances of either winning or losing the pass-line bet are 12/36 (8/36 + 4/36). As a percentage, this is exactly one-third (33.33…%). As the game continues, the odds change considerably.
