Question

Of the last 20 balloons sold at a party store, 2 were red. What is the experimental probability that the next balloon sold will be red?
Write your answer as a fraction or whole number.
P(red)=

Answer 1

To find the experimental probability of the next balloon sold being red, you can use the formula for probability:

\[ P(\text{red}) = \frac{\text{Number of red balloons}}{\text{Total number of balloons sold}} \]

From the information given:

• Number of red balloons = 2
• Total number of balloons sold = 20

Now, substituting these values into the formula, we get:

\[ P(\text{red}) = \frac{2}{20} = \frac{1}{10} \]

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

\[ P(\text{red}) = \frac{1}{10}. \]
