Solution

Let E and F denote the events that Neha and Shivani win the match, respectively.
It is clear that, if Neha wins the match, then Shivani losses the match and if Shivani wins the match, then Neha losses the match. Thus, E and F are complementary events.
Therefore,
P(E) + P(F) = 1
Since, P(E) = 0.62, therefore,
P(F) = 1-0.62 = 0.38
