question 2. If the probability of an event is P, the probability of its complementary event will be :
(a) P – 1
(c) 1 – p
correct answer answer : (c) 1 – p
explanation of correct answer :
first of all we need to consider Condition for any complimentary event
Let us consider E is any event
For the the event E this following condition is fulfill
In the given question above the probability of an event is P then the question asked us about probability of its complement that is 1 – p as we have seen in the solution.
Hence we have learnt that if the probability of an event is p then its complementary event will
be 1 – p that is given in option (c) hence option (c) 1 – p is correct answer.
