Answer 2 :

Probability for student earn grade A = $\frac{7}{12}$

Explanation :

There are total 24 students in a class.

All student appeared in a test.

14 students are got grade A

and 10 students are got grade B.

One student choose at random whose grade is A.

Probability for selected grade A student  = (total students of grade A)/(Total number of student in a class)

Probability for selected grade A student  = $\frac{14}{24} [/tex]Probability for selected grade A student =[tex] \frac{7}{12}$

Final answer.
