Question

if the probability P(E) in a certain problem is 0.3 then find P(Ē)

Answer 1

Total probability of any event is 1.
If P(E)=0.3 {given}
P(Ē) = Chance that the given event does not happen
        = 1 - P(E)
        = 1 - 0.3
P(Ē) = 0.7

Answer 2

Answer:

Step-by-step explanation:

p(e)=0.3

total number of events=1

p(-e)=1-0.3=0.7
