I believe that it is 7/26, but I think someone may still need to check my work.

Step-by-step explanation:

The first chance is 14/26, and the second is 13/25. If you incorporate those into each other, the closest option in my eyes is 7/26. However, I am not completely sure about this, so you should take this answer with a grain of salt.
