#1/36#

The probability of rolling any number on a die is #1/6#

#P(1,1) = P(1) xxP(1) = 1/6 xx1/6 = 1/36#

You can work this out without using formulae at all.

There are #36# possible combinations of numbers from rolling a die twice.

There is only one way to get a double #1#

#P(1,1) = 1/36#

The probability is the same for any double ....
