Q. 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? Simplify your answer and write it as a fraction or whole number.

\newline

P(\text{red}) = \_\_\_

Identify Total Balloons: Identify the total number of balloons sold and the number of red balloons sold. The total number of balloons sold is $20$ , and the number of red balloons sold is $2$ .
Calculate Experimental Probability: Calculate the experimental probability of selling a red balloon. The experimental probability $P$ of an event is calculated by dividing the number of times the event occurred by the total number of trials. $P(\text{red}) = \frac{\text{Number of red balloons sold}}{\text{Total number of balloons sold}}$ $P(\text{red}) = \frac{2}{20}$
Simplify Fraction: Simplify the fraction to find the simplest form of the experimental probability. $P(\text{red}) = \frac{2}{20} = \frac{1}{10}$
