Question

A party store recorded recent balloon sales.
green 20
blue 17
pink 12
purple 19
orange 7
What is the experimental probability that the next balloon sold will be green?
Simplify your answer and write it as a fraction or whole number.
P(green)=

Answer 1

To find the experimental probability of selling a green balloon, we need to determine the total number of balloons sold and the number of green balloons sold.

From the data provided:

- Green: 20
- Blue: 17
- Pink: 12
- Purple: 19
- Orange: 7

Now, let's calculate the total number of balloons sold:

\[
\text{Total balloons} = 20 + 17 + 12 + 19 + 7 = 75
\]

Next, the probability of selling a green balloon is given by the ratio of the number of green balloons sold to the total number of balloons sold:

\[
P(\text{green}) = \frac{\text{Number of green balloons}}{\text{Total number of balloons}} = \frac{20}{75}
\]

Now, we can simplify the fraction:

\[
\frac{20}{75} = \frac{4}{15} \quad \text{(by dividing both numerator and denominator by 5)}
\]

Thus, the experimental probability that the next balloon sold will be green is:

\[
P(\text{green}) = \frac{4}{15}
\]
