Question

Over the past year, Becky has enjoyed 7 of the 9 movies recommended by her local newspaper. She wants to design a spinner she can use to simulate this situation and predict the probability that she will enjoy each of the next 5 movies the paper recommends.

How should Becky divide her spinner to best simulate this situation?
2 equal-sized sections
5 equal-sized sections
7 equal-sized sections
9 equal-sized sections

Answer 1

9 equal sized sections just had the test

Answer 2

She needs to divide it into 9 equal-sized sections. Seven of the nine sections will indicate the movies she enjoyed, while 2 will indicate those she did not enjoy. She would then spin it 5 times, and for any given spin, if it lands on one of the 7 sections she enjoyed, she adds one to her count. The total count after 5 spins is a simulation of the number of movies she will enjoy.
