Answer:
Out of the 1,200 people who attended the concert in question, 0.75% would not see the band again.
Explanation:
There were 1,200 people in total at the concert and out of these, 9 people said that they would not see the band again.
In percentage terms, this is expressed as:
= Number of people who would not see band again / Total number of people who attended x 100%
= 9 / 1,200 x 100%
= 0.75 %
In conclusion, 0.75% of people who attended would not see the band again.
