Total numbers of boys in a class = 15
Number of girls in a class = 5
Total number of students = 15 + 5 = 20
Probability of getting a copy of a boy is = Total number of boys/Total number of students
= 15/20
= 3/4
Probability of getting a copy of a girl is = Total number of girls/Total number of students
= 5/20
= 1/4
∴ The probability of getting a copy of a boy is more.
