A science class has 2 girls and 2 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 boys?

THAT WILL BE 7/12*6/11 = 42 / 132

Step-by-step explanation:

1/800 is the right answer

check above link.

graphically?   well, you graph them both, the solutions is where they both intersect each other, since there are two solutions, meaning they will meet twice, or namely the linear will run into the quadratic curve twice, and where they meet, those x,y coordinates are the solutions to the system.
