To find the experimental probability \( P(pink) \), we need to determine the ratio of the number of pink golf balls to the total number of golf balls.
First, we sum up the total number of golf balls:
- Red: 2
- White: 1
- Pink: 10
- Blue: 2
- Green: 5
Calculating the total:
\[ 2 + 1 + 10 + 2 + 5 = 20 \]
Now, we have 10 pink golf balls out of a total of 20 golf balls. Thus, the experimental probability \( P(pink) \) is:
\[ P(pink) = \frac{\text{Number of pink golf balls}}{\text{Total number of golf balls}} = \frac{10}{20} = \frac{1}{2} \]
So, the probability that the next customer will receive a pink golf ball is:
\[ P(pink) = \frac{1}{2} \]
