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 = \(\frac{Total\,number\,of\,boys}{Total\,number\,of\,students}\) = \(\frac{15}{20}=\frac{3}{4}\)
Probability of getting a copy of a girl is = \(\frac{Total\,number\,of\,vowels}{Total\,number\,of\,marbles}\) = \(\frac{5}{20}=\frac{1}{4}\)
Therefore the probability of getting a copy of a boy is more.
