Question

a spinner with 4 colors is spun for a total of 50 trials. yellow was selected 10 times. what is the experimental probability of the spinner landing on yellow?
\\(\frac{2}{25})\
\\(\frac{1}{5})\
\\(\frac{1}{4})\
\\(\frac{2}{5})

Explanation:

Step1: Recall probability formula

The formula for experimental probability is $P=\frac{\text{number of favorable outcomes}}{\text{total number of trials}}$.

Step2: Identify values

The number of favorable outcomes (yellow) is 10, and the total number of trials is 50.

Step3: Calculate probability

$P=\frac{10}{50}=\frac{1}{5}$

Answer:

B. $\frac{1}{5}$
