Question

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

Answer 1

B 0.36

Explanation:

Answer 2

36%

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

`=\frac{\text{The number of students on the last row}}{\text{Total Number of Students}}\\\\=(9)/(25)\\\\=0.36\\\\=0.36 * 100\\\\=36\%`

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