The probability that the first throw of Sue is not a $6$ is $\frac56$. Then the probability that the first throw of Tim is not a $6$ is again $\frac56$.

And then the probability that for the second throw of Sue she gets a $6$ is $\frac16$.

So the total probability that all these things happen in a row is $\frac56\cdot\frac56\cdot\frac16$.
