    Re: probability

    Depends how many dice are being tossed. For two dice the most common result is 7.

    Then it's impossible to answer. The problem as you wrote it refers to "the dice" as if referring to some dice already discussed, perhaps in a previous question - are you sure there is no clue as to how many dice are involved?

    That makes it a poor problem.
    Have a look at this web page.
    The coefficients tell us the number of way we can get the various sums when four dice are used. For example the term 146x^{14} tells us there are 146 ways to throw a fourteen.

    You can change the power 4 in \left( {\sum\limits_{k = }^6 {x^k } } \right)^4 to find out the numbers for any number of dice.

    Go to that webpage. Change 4 to 2. Click the \boxed{=}
    Look for the largest coefficient.
