Amiddle school is made up of grades 6,7, and 8, and has about the same number of male and female students in each grade. explain how to use a simulation to find the experimental probability that the first 50 students who arrive are male and 7th graders

I don't really understand what it's asking
,but I think it wants me to see if it's correct or not

I think this is fully incorrect because there has to be one girl out of those 50 people and I also think that there are gonna be 5th and 6th graders in those 50 people too!

A. p = 2(l + w)p/2 - l = ww = p/2 - l b. while isolating the variable w in the equation, i first divided both sides by 2 and then i subtracted l from both sides. i hope this .
