Math & Statistics for Data Science

  1. A school contains students in grades 1, 2, 3, 4, 5, 6 and 7. Grades 2, 3, 4, 5, and 6 all contain the same number of students, but there are twice this number in grade 2. 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 grade 4?
