For better understanding think of it this way. There are hundred customers, 60 orders coffee 35 orders pie and 30 does not order pie or coffee.
This means that 70 does order coffee or pie or both. Out of those 70 people 10 will not order coffee and 35 will not order pie. Thus 70-10-35=25 will order both coffee and pie.
P=0.25
8 minutes is 480 seconds.
So if you divide 480 by 25 you get 19 with a remainder of 5/25. You can only play 19 complete commercials in 8 minutes if they are 25 seconds long.
