To find out how many girls picked a sport other than football as their favorite sport, we can look at the number of girls who chose baseball and soccer, and add those two numbers together.
From the table:
- Number of girls who chose baseball = 31
- Number of girls who chose soccer = 62
- Number of girls who chose football = 51
Now let's add the girls who chose baseball and soccer:
31 (baseball) + 62 (soccer) = 93
Thus, the number of girls who picked a sport other than football is 93.
So the answer is 93.
