Question

If p(e)=0.82,then find complementary event of p(e)

Answer 1

Given: p(e) = 0.82

To find: Complementary event of p(e).

Solution:

• Now we know that probability of any event is either equal to 0 or 1 or in between 0 to 1.

• So we have given probability of certain event as 0.82.

• We know that according to Probability concept:

                P(event) + P'(event) = 1

• So putting value of given probability, we get:

               p(e) + p'(e) = 1

                0.82 + p'(e) = 1

                p'(e) = 1 - 0.82

                p'(e) = 0.18

Answer:

             So the complementary event of p(e) is 0.18.
