Question

यदि P(E) = 0.45 तो 'E न होने की प्रायिकता ​

Answer 1

Step-by-step explanation:

$\because \: P(E) + P(E^{'}) = 1 \\ \therefore \: P(E^{'}) = 1 \: - P(E) \\ \implies \: P(E^{'}) = 1 \: - 0.45 \\ \implies \: P(E^{'}) = 0.55 \\ thus \: the \: probability \: of \: not \\ \: happenning \: the \: event \: E \: is \: 0.55.$
