To find out how many girls picked a sport other than football as their favorite sport, we need to sum the number of girls who picked baseball and soccer.
According to the table:
- Girls who picked baseball: 31
- Girls who picked soccer: 62
- Girls who picked football: 51
Now, let's calculate: Number of girls who picked a sport other than football = Number of girls who picked baseball + Number of girls who picked soccer = 31 + 62 = 93
So, the answer is 93.
