To find the experimental probability of landing on white, you can use the formula:
\[ \text{Experimental Probability} = \frac{\text{Frequency of the event}}{\text{Total number of trials}} \]
In this case, the frequency of landing on white is 45, and the total number of spins is 150.
So, the probability is:
\[ \text{Experimental Probability} = \frac{45}{150} \]
Calculating the fraction:
\[ \frac{45}{150} = 0.3 \]
To express this as a percentage, you multiply by 100:
\[ 0.3 \times 100 = 30% \]
Thus, the experimental probability of landing on white is 30%.
