A school contains students in grades 1, 2, 3, 4, 5, and 6. Grades 3, 4, 5, and 6 all contain the same number of students. There
are twice this number of students in grade 2 and three times this number in grade 1. If a student is selected at random from a list of all the students in the school, what is the probability that she will be in grade 3?
The answer is B. because if you make an equation in the form y=mx+b then you can solve the equation by inputting x where x goes in the equation and solving. BTW the equation would be y=2x-1
