Best Answer

The answer depends on what "rolling a one" refers to.

  • rolling a sum of one,
  • rolling a difference of one,
  • rolling a product of one,
  • rolling a one on one die only,
  • rolling a one on one or both dice.
Unfortunately these probabilities are different and the question is ambiguous.
