Question

according to the graph, what is the experimental probability of selecting the color red?
number of occurrences
15%
30%
35%
50%

Explanation:

Step1: Calculate total number of occurrences

Add the number of occurrences of all colors: \(12 + 8+14 + 6=40\)

Step2: Calculate probability of red

The number of red occurrences is \(6\). The formula for experimental probability \(P=\frac{\text{Number of favorable outcomes}}{\text{Total number of outcomes}}\). So \(P=\frac{6}{40}\)

Step3: Convert to percentage

\(\frac{6}{40}=0.15\), and \(0.15\times100\% = 15\%\)

Answer:

15%
