Hi!
Since there are 32 students in the class, and each one of them spun the spinner 25 times, the total amount of time that spinner was spun is 32 * 25 = 800. It landed on seven 95 times, so the experimental probability is:
95/800 = 19/160 = 0,11875 = 11,875% or approximately 11,9%
The correct answer is 11,9%.
Hope this helps!
