A survey was taken on 30 classes at a school to find the total number of left-handed students in each class. The table below shows the results:
|No. of left-handed students||0||1||2||3||4||5|
|Frequency (no. of classes)||1||2||5||12||8||2|
A class was selected at random.
Find the probability that the class has 2 left-handed students.
