Question

If P(A) and P(¯¯¯¯A) are complementary events and P(A) =  0.15, then P(¯¯¯¯A)= ?


  1. 0.35

  2. 0.3

  3. -0.15

  4. 0.85


Solution

The correct option is D

0.85


Given,

P(A) = 0.15
Since P(A) and P(¯¯¯¯A) are complementary events,

P(A) + P(¯¯¯¯A) = 1

Because the sum of probabilities of an event and its complementary event is always 1.

P(¯¯¯¯A) = 1  P(A) = 1 – 0.15 = 0.85
