What is the probability of having these 2 sets of numbers with 4 digits the same and 1 unique digit? Thank you.
Welcome to MHB.
The two numbers have the digits 1,2,4, and 5 as the same. So is the question what is probability of a 5 digit number containing 1,2,4,5 and two other digits with order not mattering? Or is it having 4/5 digits matching in general?
