Question

 
This table displays the frequency of the spinner landing on different colors
Colors Where the Spinner Stopped Frequency
blue 20
red 15
green 45
yellow 10
black 15
white 45
Total 150
A color wheel with six equal sections, blue, red, green, yellow, black, and white, was spun 150 times. The results are summarized in the table.
What is the experimental probability of landing on white? Express your answer in percent form.(1

Answer 1

To find the experimental probability of landing on white, you use the formula for experimental probability:

\[ P(\text{event}) = \frac{\text{Frequency of the event}}{\text{Total frequency}} \]

In this case, the frequency of landing on white is 45, and the total frequency of spins is 150.

So, the probability is calculated as follows:

\[ P(\text{white}) = \frac{45}{150} \]

Now, simplify the fraction:

\[ P(\text{white}) = \frac{45 \div 15}{150 \div 15} = \frac{3}{10} \]

To convert this probability into percent form, you can multiply by 100:

\[ P(\text{white}) = \frac{3}{10} \times 100 = 30% \]

Thus, the experimental probability of landing on white is 30%.
