Question 325140
This is a really poor question.
I suspect the problem expects you to use the following logic.
There were 24 outs, of which 17 were fly balls. So that leaves 7 groundball outs.
If that is the case, then the infielders made 7 groundball outs. If their out totla had 50% flyball outs, that means the infield had the same number of groundball outs as flyball outs (7). Total 14 infield outs.
If you subtract the 7 infield fly outs from the total fly outs, (17-7) that means there were 10 outfield fly outs.

So why is the is a poor question?
Because there was nothing in the question to say that the 7 outs that were not fly outs were, in fact, ground outs to the infield. What about Strikeouts? What about runners caught stealing? What about all the other wierd sorts of outs that 'can' happen in baseball.
