After playing 2 matches possible outcomes are:
water polo team wins none, wins 1 or wins both games.
chance that they win both matches are:
0.44*0.44 = 0.1936 in relative value
Chance that they lose both matches are:
(1-0.44)*(1-0.44) = 0.3136 in relative value
If we multiply these relative values by number of matches and subtract that from number played double games (10000) we will get number of times they won only once.
10000 - 10000* (0.3136+ 0.1936) = 4928
Answer is D.
