Bob’s spun a spinner with six equal sections 150 times in recorded the results. What is the experimental probability of landing on green?
|Colors where the spinner stopped| Frequency|
| Blue| |20|
| Red.|. | 15|
| Green|. |45|
| Yellow|. |10|
| Black|. |15|
| White| |45|
Total: 150
A. 45%
B. 30%
C. 3%
D. 0.45%
The experimental probability of landing on green can be calculated by taking the frequency of landing on green (45) and dividing it by the total number of spins (150):
Experimental probability = Frequency of green / Total spins
Experimental probability = 45 / 150
Experimental probability = 0.30 or 30%
Therefore, the correct answer is B. 30%.
