To find the experimental probability of landing on white, you can use the formula:
\[ \text{Experimental Probability} = \frac{\text{Frequency of the event}}{\text{Total frequency}} \]
In this case, the frequency of the spinner landing on white is 45, and the total frequency is 150.
\[ \text{Experimental Probability of white} = \frac{45}{150} \]
Next, to calculate this probability as a percentage, you would multiply by 100:
\[ \text{Experimental Probability of white} = \left(\frac{45}{150}\right) \times 100 \]
Calculating this gives:
\[ \frac{45}{150} = 0.3 \]
So,
\[ 0.3 \times 100 = 30% \]
Thus, the experimental probability of landing on white is 30%.
