There are two 5th grade classes at Jones Elementary School. Mrs. Roberts has 17 girls and 18 boys in her class. Mr. Simpson has 16 boys and 19 girls in his class. If a 5th grade student is selected at random, what is the probability that it will be a girl? Give the answer as a fraction in simplest form.
you add all of the girls then you and all of the boys. There are 20 girls and there are 34 boys. You would divide both of them by two. then the fraction that you will get is 10/ 17.
