Question

a spinner has the colors red, orange, yellow, and green. the spinner is spun 30 times, and it lands on red 12 times. what is the experimental probability of spinning a red? $\frac{4}{15}$ $\frac{2}{5}$ $\frac{1}{3}$

Explanation:

Step1: Recall experimental - probability formula

Experimental probability = $\frac{\text{Number of favorable outcomes}}{\text{Total number of trials}}$

Step2: Identify values

Number of favorable outcomes (lands on red) = 12, total number of trials = 30

Step3: Calculate probability

$\frac{12}{30}=\frac{2}{5}$

Answer:

$\frac{2}{5}$
