To find out how many girls picked a sport other than football as their favorite sport, we can sum the number of girls who picked baseball and soccer.
From the table:
- Girls who picked baseball: 31
- Girls who picked soccer: 62
- Girls who picked football: 51
Now, we add the numbers of girls who picked baseball and soccer: 31 (baseball) + 62 (soccer) = 93
Therefore, the number of girls who picked a sport other than football is 93.
