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"`

Answer 1

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
