In the lesson of Venn diagram, I have mentioned that while filling the values in the diagram first enter the common data ....here common data i.e. the value in intersection part is 30(as 30 students pass both) then fill the value for students passed in first exam which is 30( 60- no. of students passed in both) similarly for no. of students passed in second exam(20=50-30). probability that a student passed in atleast one exam= (students passed in first exam only+student passed in second exam only+student passed in both exams)/total students.....=(30+20+30)/100..=0.8
