Explanation / Answer

Now,

s denotes the success of a read operation

f denotes the failure of a read operation

S denotes the success of an error recovery procedure

F denotes the failure of an error recovery procedure

A denotes abort message sent to the operator

A sample place is the set of all possible values that an experiment can take in order to generate an output, they can be visualized as inputs to a function.

So the sample space of this expt. will be as follows

SS = [ {s,s,s,s},{s,s,s,f},{s,s,f,s},{s,f,s,s},{f,s,s,s},{s,s,f,f} ..... {f,f,f,f} ]

When the last possible outcome of {f,f,f,f} is reached it will trigger a new sample space given by

{f,f,f,f} = [ {S,S,S,S},{S,S,S,F}....{F,F,F,F} ]

Again when the last outcome is reached it will trigger the outcome

{F,F,F,F}= A

Thus the sample space for this experiment will follow a tree structure as outlined above, with all the possible outcomes and sub-outcomes as defined in the experiment.
