HTET 2025 Level 1 PRT Question Paper (5-Jul-2026)
The correct answer is
0.0001
The probability of an event always lies between 0 and 1; a value closer to 0 indicates that the event is less likely to occur, while a value closer to 1 indicates it is more likely to occur.
Among the given options, \(0.0001\) is the smallest value, so it represents the lowest chance of occurrence.
Therefore, an event that is most unlikely to happen has probability \(0.0001\).
