From the question
The probability a student at school A is in grade 10 is
From the table
Number of students in grade 10 at school A = 25
Total number of students in School A = 120
Therefore
The probability a student at school A is in grade 10 is
[tex]\frac{25}{120}=\frac{5}{24}[/tex]
Hence, The probability a student at school A is in grade 10 is 5/24
The probability a student at school B is in grade 10 is
From the table
Number of students in grade 10 at school B = 20
Total number of students in School A = 80
Therefore
The probability a student at school B is in grade 10 is
[tex]\frac{20}{80}=\frac{1}{4}[/tex]
Hence, The probability a student at school B is in grade 10 is 1/4
Since, the probability a student at school B is in grade 10 is greater than the probability a tudent at school A is in grade 10 then
It is less like
