number of boys in the class, = 55%

number of girls in the class, = 45%

number of the boys who scored A = 25%

number of girls who scored A = 35%

To find:

the probability that a girl chosen scored A

The fraction of the boys who score A:

[tex]= \frac{25}{55} = \frac{5}{11}[/tex]

The fraction of the girls who scored A:
