Amath class has 4 girls and 4 boys in the seventh grade and 3 girls and 5 boys in the eighth grade. the teacher randomly selects a seventh grader and an eighth grader from the class for a competition. what is the probability that the students she selects are both girls? write your answer as a fraction in simplest form.

Hey there :)

Math class:
7th grade = 4 girls and 4 boys          Total students in grade 7 → 4 + 4 = 8
8th grade = 3 girls and 5 boys          Total students in grade 8 → 3 + 5 = 8

Fraction of girls in 7th grade = 
Fraction of girls in 8th grade = 

Teacher randomly chooses a 7th and 8th grader.
Therefore the probability will be:
P = girls of 7th grade x girls of 8th grade
 
P =  × 
   = 

What’s the equation you are trying to solve to get x?
