Question 23 • Math Models A

Vince makes 75% of his free throw attempts. He wants to create a tool that will simulate his free throw shooting and allow him to predict the probability that he will make 6 of his next 7 free throw attempts.Which spinner simulation uses an appropriate device and has the correct number of trials?

Answer
A
a spinner divided into 2 congruent sectors, spun 6 times
B
a spinner divided into 2 congruent sectors, spun 7 times
C
a spinner divided into 4 congruent sectors, spun 6 times
D
a spinner divided into 4 congruent sectors, spun 7 times

Explanation

Vince makes 75% of his free throws, and 75% equals 3 out of 4. A spinner divided into 4 equal sectors can represent this chance by assigning 3 sectors to a made shot and 1 to a miss. Since he wants to simulate his next 7 attempts, the spinner must be spun 7 times. Therefore, the correct choice is a spinner divided into 4 congruent sectors, spun 7 times.
