Question

If P(E)=0.85 , what is the probability of E ?​

Answer 1

Answer:

P(E)+P(Ē)=1

0.85+P(Ē)=1

P(Ē)=1-0.85

P(Ē)=0.15

Answer 2

Step-by-step explanation:

We know that the sum of the probabilities of all the elementary events of an experiment is 1.

If an experiment has two elementary events say E & not E then,

P(E)+P(notE)=1⟹P(notE)=1−P(E)

Given P(E)=0.05

∴P(notE)=1−0.05=0.95
