The results of surveying some members of a concert audience are told below, how many people are in the?

sample? when asked if they enjoyed the concert, 38 said yes, and 12 said no [38 or 12 or 50 or 26?


what is the probability that a person in the audience enjoyed the concert[ 19/25 or 6/19 or 19/6 or 6/25?


predict how many of the 725 people in the audience would say they enjoyed the concert [229 or 114 or 551 or 605? if possible explain how you came up with results, 10 points automatically

The results of surveying some members of a concert audience are told below, how many people are in the?
38 out of 50 enjoyed the concert. When this fraction is reduced, you get a probability of 19/25. To predict how many out of 725 would enjoy the concert, one would need to see how many times 25 goes into 725, which would be 29. Finally, multiply 19 by 29 to get 551. So approximately 551 out of 725 people would enjoy the concert.








P.S. Isn't this a math question?
