Question

If P (E)=0.01, what is the probability of 'not E'?

যদি P (E)=0.01, তেন্তে   'E নহয়'ৰ সম্ভাৱিতা কি?

(a) 0.95  (b) 0.99 (c) 1.01 (d) 1.99

Answer 1

Correct answer is (a) 0.99

Solution:

P(Not E) = 1 - P(E)

               = 1 - 0.01

               = 0.99

 Therefore, the probability of not E is 0.99.
