One week, a librarian kept track of whether returned books were returned on time or not, and whether they had fewer than 200 pages or they had 200 pages or more. The results are shown on the table.

What is the probability that a randomly selected book returned that week was returned on time, given that it had 200 pages or more?

let x be the money she spent so that she can earn the free t-shirt.

since, she already spent $112.49

⇒

also, as per the statement: jennifer must spend $250 or more in order to qualify for a free t-shirt at the store.

then,

inverse property is the answer
