Scott repeatedly rolls a pair of standard six-sided dice and keeps track of the sum of the two numbers rolled each time. So far he has not rolled any sum twice. What is the maximum possible number of times he has thrown the dice?

This question appears to be off-topic. The users who voted to close gave this specific reason:
- "This question is off-topic as it appears to be a mathematics problem, as opposed to a mathematical puzzle. For more info, see "Are math-textbook-style problems on topic?" on meta." – JonMark Perry, Deusovi
So there are
11 different outcomes for 6-sided pairs of dice, from 2 to 12. He could therefore have rolled the dice a maximum of 11 different times to get each of the different outcomes exactly once.
