Question

Compare the probability that a randomly selected student is in grade 10 at each school. Move options to the blanks to complete thesentences.

Answer 1

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

`(25)/(120)=(5)/(24)`

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

`(20)/(80)=(1)/(4)`

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
