total no. of students =45
no. of student plays cricket =10
no. of student plays football =15
no. of student plays volley ball =15
no. of student plays badminton =15
no.of possible outcome=10+15=25(as we add no of student playing football or cricket.)
no.of total outcome=45
P(E)=no of possible outcome/total no of outcome
=25/45
=5/9
so probability of that they are playing or cricket is 5/9.
