Define Conditional POS.

• A. Cumulative probability to date of the search object being located, assuming it is the given type
• B. Probability of future success
• C. Probability of locating in the next phase
• D. Probability of overall search success

Answer: (A)

Conditional POS is the probability of locating the search object given that it is of a specific type and based on information accumulated up to the current date. It’s a cumulative measure, reflecting what has been learned and how likely it is that the object has already been found if that type is true. This is different from a purely future-looking probability, a phase-specific probability, or an overall unconditional probability.

That’s why describing it as the cumulative probability to date of the object being located, assuming it is the given type, matches the concept best. The other ideas refer to future prospects, a single future phase, or the total, unconditional chance, which are distinct quantities.
