To find "one in how many" for the probability calculated, you can take the reciprocal of the probability. 

The probability we calculated for getting exactly 3 characters in 11 attempts is approximately 0.007944.

So, the reciprocal is:

\[
\frac{1}{0.007944} \approx 125.88
\]

Therefore, you would expect to get exactly 3 characters in 11 attempts approximately once in every 126 sets of 11 attempts.
