Answer:
1/216
Step-by-step explanation:
n{1111,2222,3333,4444,5555,6666}=6
number of every cases =6×6×6×6
6/6^4=1/6^3=1/216
the anwser would most likely be 3 because you want the LCM
Table B. The same input can't go to different outputs

We effectively rewrite the equation as

In order for the LHS to be defined, we need to restrict
, or
. Now, the LHS will vanish when the numerator is 0, which happens for

This value is indeed smaller than 4, so the solution is
.
