Quiz 2 has 25% of students 90 and above whereas the Quiz 1 has Q3 as 95 which means 90 starts even before Q3. So Quiz 1 has more students whose score is 90 and above.Work: Since the Q2 for Quiz 1 is 60 and Q2 for Quiz 2 is 50.

P(A)=n(A)/N=200/1000=0.2, P(B)=n(B)/N=100/1000=0.1 and P(A??B)=n(A??B)/N=80/1000=0.08.
