Ten not welcomed... (Posted on 2023-08-30) Difficulty: 3 of 5
The standard 52-card deck will represent a database consisting of 4 identical sets each containing a set of 13 integers: Ace=1, 2 to 10 represent respectively the numerical values, J=11, Q=12 and K=13.
Drawing randomly 2 cards you get two numbers, say n1 and n2. Evaluate the absolute value of d=n1-n2.

What is the probability that d will not be equal to 10?

Please solve analytically and use a simulation program to validate your results.
