The table gives the distribution of votes for a new school mascot and grade level for 80 students. Grade level Mascot Sixth Seventh Eighth Total Badger 4 9 9 22 Lion 9 2 9 20 Longhorn 4 6 4 14 Tiger 6 9 9 24 Total 23 26 31 80 If one of these students is selected at random, what is the probability of selecting a student whose vote for new mascot was for a lion?
Correct answer: C (parsed from the explanation — this source omits an answer key for this item)
Explanation
Choice C is correct. If one of these students is selected at random, the probability of selecting a student whose vote for the new mascot was for a lion is given by the number of votes for a lion divided by the total number of votes. The given table 20 indicates that the number of votes for a lion is votes, and the total number of 80 80 votes is votes. The table gives the distribution of votes for students, and the table shows a total of 80 votes were counted. It follows that each of the 80 students voted exactly once. Thus, the probability of selecting a student 20 1 whose vote for the new mascot was for a lion is 80, or 4. Choice A is incorrect and may result from conceptual or computational errors. Choice B is incorrect and may result from conceptual or computational errors. Choice D is incorrect and may result from conceptual or computational errors.
