Well, let's see. He has a 1 in 26 chance. The small prize is getting the letter right, but not getting both of the numbers right. So he has a 1 in 26 chance of getting the letter right. But we're not done here just with the 1 in 26. Because this 1 in 26, this includes all the scenarios where he gets the letter right, including the scenarios where he wins the grand prize, where he gets the letter and he gets the two numbers right. So what we need to do is we need to subtract out the situation, the probability of getting the letter and the two numbers right.
