Heya .....here is ur answer
Step-by-step explanation:let total no. of students=x
Probability that they will pass an exam =0.6
No. of students who failed an exam =20
No. of students who passed the exam =x-20
Probability of a student passing = no. of students who passed/ total no. of students
0.6=x-20/x
0.6x =x-20
0.4x=20
x=50
Thus, total no. of students in class =50
