To explain, 30% of those who read A but not B look into advertisements -

P(Ads | A only) means probability of people watching ads when they read only 'A' newspaper which is 30% but you have to find out this percentage out of all the people reading only 'A' newspaper so we will multiply by 17% (people reading only 'A' newspaper) which means 30% of 17% people reading only 'A' newspaper watch Advertisements

The same will be followed for people reading only 'B' newspaper and both 'A & B' newspaper.
