The first pseudocode is correct because it initializes the state as Operational $($O$)$ and correctly simulates the transitions based on the given probabilities.

The second pseudocode is correct because it starts the simulation in Failure $($F$),$ which makes more sense, and the state transitions are accurate.

The first pseudocode is wrong because the system should always start in the Failure $($F$)$ state, and the transition probabilities are incorrect.

The second pseudocode is wrong because it starts in Failure $($F$)$ and does not handle state transitions correctly between Operational $($O$)$ and Failure $($F$).$
