Answer:

choice D) 42 is the final answer.

Step-by-step explanation:

Population of the school = 350

Debra finds that the probability that a student has more than three siblings is [tex]=\left(\frac{3}{25}\right)[/tex]

Then the number of students that we expect to have more than three siblings, based on Debra's experiment [tex]=350\cdot\left(\frac{3}{25}\right)[/tex]

[tex]=\left(\frac{1050}{25}\right)[/tex]

[tex]=42[/tex]

Hence choice D) 42 is the final answer.
