Question

If P(E) = 0.005, then the probability of "not E” is:
(A) 0.05
(B) 0.5
(C) 0.995
(D) 0.95​

Answer 1

$\huge{\mathcal{\green{\underline{Answer}}}}$

p(not E ) = 1 - p(E)

p(not E ) = 1 - 0.005

$\huge{\mathcal{\implies{\green{\underline{p(not\:E)=0.995}}}}}$

Answer 2

P (not E) = 1- P (E)

= 1 - 0.005

= 0.995

The correct answer is option c.
