Two players, Sania and Sonali play a tennis match. It is known that the probability of Sania winning the match is 0.69. What is the probability of Sonali winning ?

Solution:

Probability of Sania winning the match, P(E) = 0.69

Probability of Sonali winning = Probability of Sania losing,

= 1-0.69

= 0.31

Hence the probability of Sonali winning is 0.31.
