To find how many girls picked a sport other than football as their favorite sport, we can look at the numbers provided in the table:
- Girls who picked baseball: 31
- Girls who picked soccer: 62
- Girls who picked football: 51
First, we need to calculate the total number of girls who picked a sport other than football. We can do this by adding the number of girls who picked baseball and soccer:
\[ \text{Girls who picked a sport other than football} = \text{Girls who picked baseball} + \text{Girls who picked soccer} \] \[ = 31 + 62 \] \[ = 93 \]
Thus, 93 girls picked a sport other than football as their favorite sport.
