A number color spinner was spun 20 times:

1 (Yellow) was spun 3 times
2 (Red) was spun 1 time
3 (Aqua) was spun 4 times
4 (Red) was spun 2 times
5 (Blue) was spun 0 times
6 (Aqua) was spun 3 times
7 (Blue) was spun 5 times
8 (Red) was spun 2 times

What is the experimental probability of spinning the color blue?

•  $\frac{5}{8}$  

•  $\frac{2}{20}=\frac{1}{10}$  

•  $\frac{0}{20}=0$  

•  $\frac{5}{20}=\frac{1}{4}$
