    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.
