Solution

The correct option is A $1 - p$
For any event,
$P (Happening event) + P (Not happening event) = 1$
$P (Happening event) = 1 - P (Not happening event)$
$P (Not Happening event) = 1 - P (Happening event)$
Since, $P (Happening event) = p$
$∴ P (Not Happening event) = 1 - p$

If the probability of happening of an event is p, then the probability of its not happening is

The correct option is A 1−pFor any event,P(Happening event)+P(Not happening event)=1P(Happening event)=1−P(Not happening event)P(Not Happening event)=1−P(Happening event)Since, P(Happening event)=p∴P(Not Happening event)=1−p

The correct option is A $1 - p$
For any event,
$P (Happening event) + P (Not happening event) = 1$
$P (Happening event) = 1 - P (Not happening event)$
$P (Not Happening event) = 1 - P (Happening event)$
Since, $P (Happening event) = p$
$∴ P (Not Happening event) = 1 - p$
