Answer:

192 fans would not be wearing a hat

Step-by-step explanation:

"9 out of 25 were wearing hats" implies that 16 were not wearing hats.  This, the empirical probability that a subject picked at random is not wearing a hat is 16/25, or 0.64.  

This is the fraction of those 300 fans who I expect will not be wearing a hat:

0.64(300 fans) = 192 fans would not be wearing a hat.
