Question

If p(e)=0.23,what is probability of not e

Answer 1

Answer:

P(E) = 1

For not e, P(e) = 1 - 0.23 = 0.77

Answer 2

$\large \bold{ \underline{ \underline{ \: Answer : \: \: \: }}}$

$\to$ Probability of not happening of an event is 0.77

$\large \bold{ \underline{ \underline{ \: Explaination: \: \: \: }}}$

Given ,

P ( E ) = 0.23

We know that ,

$\large \bold{ \fbox{ \fbox{ \: \: P ( E ) + P ( Not \: E ) = 1 \: \: }}}$

$\to$ P ( Not E ) = 1 - 0.23

$\to$ P ( Not E ) = 0.77

Hence , probability of not happening of an event is 0.77
