Sangeeta and Reshma, play a tennis match. It is known that the probability of Sangeeta winning the match is 0.62. What is the probability of Reshma winning the match?

Step 1: Understand the question and make a note of the important points
GIVEN: Sangeeta and Reshma, paly a tennis match
The probability of Sangeeta's winning chances = P(S) = 0.62
ASSUME : Let S and R denote the events that Sangeeta wins the match and
Reshma wins the match, respectively.
Step 2: Determine the probability of the Reshma's winning chance
FORMULA: We denote the event 'not E' by \bar{E}. This is called the complement event of event E.
So, P(E) + P(not E) = 1
Here, Rashma's winning chance is compliment event to sangeeth's winning chance.
So, P(R) + P(S) = 1
The probability of Reshma's winning chances = P(R) = 1 - P(R)
= 1 - 0.62
= 0.38
