In a bag of 25 marbles, 5 are red, 7 are blue, 10 are green, and 3 are yellow. The results of a marble being randomly selected and replaced 50 times are shown in the table. For which color is the experimental probability closest to the theoretical probability of being selected?
Color Frequency
Red 18
Blue 10
Green 15
Yellow 7
A.
Red

D.
Yellow
B. Blue
The theoretical probability of selecting a blue marble is 7/25, which is approximately 0.28. The experimental probability of selecting a blue marble is 10/50, which is also 0.20. This means that the experimental probability of selecting a blue marble is closest to the theoretical probability compared to the other colors.
