Q. There are

8

children in Sophie's preschool class. During free time yesterday,

1

of them chose to read books. What is the experimental probability that a randomly selected preschooler would choose to read books today? Simplify your answer and write it as a fraction or whole number.

\newline

P(\text{read books}) = \_\_\_

Identify Total Outcomes: Identify the total number of outcomes. In this case, the total number of children in Sophie's preschool class is the total number of possible outcomes when selecting a child at random. $\newline$ Total number of outcomes $=$ Total number of children $= 8$
Identify Favorable Outcomes: Identify the number of favorable outcomes. The number of children who chose to read books yesterday is the number of favorable outcomes for the event of a child choosing to read books today. $\newline$ Number of favorable outcomes = Number of children who read books yesterday = $1$
Calculate Experimental Probability: Calculate the experimental probability. The experimental probability is the ratio of the number of favorable outcomes to the total number of outcomes. $\newline$ P( $\text{read books}$ ) = Number of favorable outcomes / Total number of outcomes $\newline$ P( $\text{read books}$ ) = $\frac{1}{8}$
Simplify Probability: Simplify the probability if necessary. In this case, the fraction $\frac{1}{8}$ is already in its simplest form, so no further simplification is needed.
