Solution

The correct option is C
1/4

Total number of students = 100

Percentage being girls = 25% = $\frac{25}{100}$

Number of girls = $\frac{25}{100} \times 100$

So probability of selecting a girl = $\frac{t o t a l n u m b e r o f f a v o u r a b l e o u t c o m e s}{t o t a l n u m b e r o f o u t c o m e s}$

= $\frac{Number of girls}{Total number of students}$

= $\frac{25}{100}$ = $\frac{1}{4}$
