EXPLANATION

We first need to fill all the values in the table, by adding the terms in the corresponding total boxes, as shown as follows:

Then, if we need to know the number of students that are junior, we must divide the total of the junior column with the total number of students, as follows:

Therefore, P(Junior) = 8/30 = 4/15 = 0.2666

Expressing as a percentage and rounding to the nearest whole number:

P(Junior) = 27%
