Question
If the probability of an event is p, the probability of its complementary event will be ______.
Options
p – 1
p
1 – p
`1 - 1/"p"`
Solution
If the probability of an event is p, the probability of its complementary event will be 1 – p.
Explanation:
Since, probability of an event + probability of its complementary event = 1
So, probability of its complementary event = 1 – probability of an event = 1 – p
