Amath class has 7 girls and 5 boys in the seventh grade and 4 girls and 4 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.

11 out of 20 or 11/20

Step-by-step explanation: Well there is 11 girls in both grades and there is 20 students in total

option a.

step-by-step explanation:

if you look closely at the graph, we can notice that the function is not defined at two different points.

if you look at functions b and c, you will notice that both functions are not defined at just one point. the function b is not defined at x= -5/2 and function c is not defined at x=-5. both options are discarded, given that our function should not be defined at two fiferent points.

now, if you look closely at the graph you will notice that the function sketched is not defined at x=5 and x=-2.

the equation is not included but the answer is (1.50, 2.00, 2.75)
