Question

If P(E) = 0.05, what is the probability of 'Not E'?

যদি P (E)=0.05, তেন্তে 'E নহয়'ৰ সম্ভাৱিতা কি?

(a) 0.95  

(b) 0.99

(c) 1.02

(d) 1.99

Answer 1

Correct answer is (a) 0.95

Solution:

we know,

P ( E) + P (Not E) = 1

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

                 = 1 - 0.05

                 = 0.95

Therefore, the probability of not E is 0.95.
