Question

If P(E)=0.05, what is the probability of 'not E'?​

Answer 1

Step-by-step explanation:

The sum of the probability for an event to occur and the probability for the same event not to occur is equal to 1. Thus, the probability of 'not E' is 0.95

Answer 2

$we \: know \: that \: the \: probability \: of \: \\ anything \: \: happening \: \\ guarantedly is \: 1$

$p(\:E) + p(not \: E ) = 1$

$p \: (not \: E) = 1 - p(E)$

$= 1 - 0.05$

$= 0.95$

$the \: probability \: of \: 'not \: E' is\: 0.95$
