Question

Danielle has pink, yellow, white, and orange golf balls in her golf bag. She pulls out one golf ball at a time and replaces it.

Danielle recorded the results of 20 draws in the table below.

Draw Result Draw Result Draw Result Draw Result
1 white 6 pink 11 orange 16 yellow
2 pink 7 orange 12 pink 17 pink
3 orange 8 white 13 yellow 18 white
4 orange 9 orange 14 pink 19 orange
5 white 10 yellow 15 orange 20 pink

What is the experimental probability of drawing a pink golf ball?
A.
7/20
B.
1/5
C.
3/10
D.
3/20

Answer 1

To calculate the experimental probability of drawing a pink golf ball, we need to determine how many times a pink golf ball was drawn out of the total draws.

From the results recorded, let's count the occurrences of each color:

- Pink: 7 times
- Yellow: 4 times
- White: 5 times
- Orange: 4 times

Now we can calculate the experimental probability of drawing a pink golf ball. The formula for experimental probability is:

\[
\text{Probability of an event} = \frac{\text{Number of favorable outcomes}}{\text{Total number of trials}}
\]

For pink golf balls:
- Number of favorable outcomes (pink) = 7
- Total number of trials = 20

So the probability is:

\[
\text{P(pink)} = \frac{7}{20}
\]

Thus, the experimental probability of drawing a pink golf ball is:

**A. \( \frac{7}{20} \)**
