Calculating Probability for Two Events: Longer Than 24.5 Minutes

[synkk]

As the question says the probability that both of them were longer than 24.5 minutes i'd of thought it would be in the 24-29 row, so that means 8/55 * 7/54, but the answer is 11/55 * 10/54, where did they get 11 from?

How many ways are to choose 2 from the over 24.5 minute group? How many ways are there to choose 2 overall?
