Given:

A standard pair of six-sided dice is rolled.

Total number of outcomes is 36.

n(S)=36

To find the probability of rolling a sum greater than or equal to 11:

Here, A= {(5, 6), (6,5), (6, 6)}

So, n(A)=3

Hence, the probability of rolling a sum greater than or equal to 11 is,


\begin{gathered} P(A)=(n(A))/(n(S)) \\ =(3)/(36) \\ =(1)/(12) \end{gathered}

Hence, the answer is,


(1)/(12)
