Probability = 0
Step-by-step explanation:
If something happening is impossible, it's probability of occurring is also 0.

Since we are not replacing the cards once we pick them, this event is impossible to occur.
 
        
             
        
        
        
You can calculate the difference/vector of both points:

then calculate the magnitude/length like pythagoras
