Question

In a T.T. match between Geeta and Ritu, the probability of the winning of Ritu is 0.73. Find the probability of:

1. winning of Geeta.
2. not winning of Ritu.

Answer 1

i. Winning of Geeta is a complementary event to winning of Ritu

Therefore,

P(winning of Ritu) + P(winning of Geeta) = 1

P(winning of Geeta) = 1 – P(winning of Ritu)

P(winning of Geeta) = 1 – 0.73

P(winning of Geeta) = 0.27

ii. Not winning of Ritu is a complementary event to winning of Ritu

Therefore,

P(winning of Ritu) + P(not winning of Ritu) = 1

P(not winning of Ritu) = 1 – P(winning of Ritu)

P(not winning of Ritu) = 1 – 0.73

P(not winning of Ritu) = 0.27
