Answer:
Ok so if this is a question then the probalility will probably be 1/3 for three of the 6 sides.
Step-by-step explanation:
We actually don't need to do any computation. By definition, the inverse function
changes the role of input and output. So, if a function f maps x onto y, the inverse function maps y onto x.
You have to think like this: if the function makes a step further, the inverse function makes that same step back.
This means that the composition
is always the identity function
. In fact,

So, for every function, you have
