If probability of an event 'E' is P(E)=0.6 then find P (not E)?
Most Upvoted Answer
If probability of an event 'E' is P(E)=0.6 then find P (not E)?
An event must either occur (E) or not occur (!E)

Therefore the sum of the probabilities of an event occurring and an event not occurring must be equal to 100%

That is P(E)+P(!E)=1.00

Given that P(E)=0.60
This implies that
P(!E)+0.60=1.00

P(!E)=0.40

If probability of an event 'E' is P(E)=0.6 then find P (not E)?
P(E) + P( not E) = 1
0.6 + P( not E) = 1
P( not E) = 1- 0.6
= 0.4
