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
