A teacher writes the name of each of her 25 students on a slip of paper and places the papers in a box. To call on a student, she draws a slip of paper form the box. Each paper is equally likely to be drawn, and the papers are replaced in the box after each draw. If there are 9 students in the last row, what is the probability of calling on a student in the last row

Respuesta :

Answer:

36%

Step-by-step explanation:

Total Number of Students = 25

The number of students on the last row = 9

The probability of calling a student in the last row

[tex]=\dfrac{\text{The number of students on the last row}}{\text{Total Number of Students}}\\\\=\dfrac{9}{25}\\\\=0.36\\\\=0.36 \times 100\\\\=36\%[/tex]

The probability of calling a student in the last row is 36%.
