The wording is distracting. If it had said,

then I would say the answer is 1/11, since there are 11 ways that two dice could show at least one six, but only one of them in which both dice are sixes.
On the other hand, if it said,

then the answer would be 1/6. After you remove one die, the odds that the other one is a six is the same as rolling that die by itself.
The odds where
at least one is a 6 are different from where
this one is a 6. The way the problem is worded, I'd say that the act of removing one of the dice makes the odds of the other one being a six 1/6.
