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. And we already know what that is. It's 1 in 2,600. So it's 1 in 26 minus 1 in 2,600. The reason why I have to subtract out this 2,600 is he has a 1 in 26 chance of getting this letter right. So that includes the scenario where he gets everything right. But the small prize is only where you get the letter and one or none of these.
