To calculate the experimental probability of landing on white, you can use the formula for probability:
\[ P(\text{color}) = \frac{\text{Frequency of the color}}{\text{Total spins}} \]
In this case, the frequency of landing on white is 45, and the total number of spins is 150.
So, the probability \( P(\text{white}) \) is:
\[ P(\text{white}) = \frac{45}{150} \]
Now, calculating this gives:
\[ P(\text{white}) = 0.3 \]
To express the probability in percent form, you multiply by 100:
\[ P(\text{white}) \times 100 = 0.3 \times 100 = 30% \]
Therefore, the experimental probability of landing on white is 30%.
