We Dropped Dr Zonga

Oops...

We made a welcome-home sign for Dr Zonga using an A4 page for each letter in his/her name.  Unfortunately, we dropped them on the floor - all face down and totally random in their order.  

If we pick them up, one by one, what is the probability that we pick the letters up in exactly the correct order?  

Think you've got the answer?
