Q. Ann runs a day care center. Of the last

18

children to enroll at the day care center,

8

of them have been elementary school students. Considering this data, how many of the next

9

children to enroll should you expect to be elementary school students?

\newline

____ elementary school students

\newline

Calculate Total Children: First, let's find out the total number of children who enrolled at the day care center. We know $8$ were elementary students and the rest were not mentioned, but the total given is $18$ . So, the calculation is: $\newline$ $8$ (elementary students) + ( $18 - 8$ ) (other children) = $18$ .
Calculate Probability: Next, we calculate the probability that an enrolled child is an elementary school student. We use the number of elementary students and the total number of children: $\newline$ Probability = Number of elementary students / Total number of children = $\frac{8}{18}$ .
Calculate Expected Number: Now, we need to find out how many of the next $9$ children we can expect to be elementary students based on the probability. We multiply the probability by the number of new children: $\newline$ Expected number of elementary students = $(\frac{8}{18}) \times 9$ .
