Let's say we have two ordered 4-tuple and each has 4 numbers like $t_1: (n_1,n_2,n_3,n_4)$ and $t_2: (m_1,m_2,m_3,m_4)$. range for $n_i$ and $m_i$ is $[0,100]$ (whole numbers so no decimals). I want to know what is the probability that the two of them are same if the numbers are selected from the given range i.e. $n_1=m_1$, $n_2=m_2$, $n_3=m_3$, $n_4=m_4$.
Some notes: We are choosing with replacement and order does matter.
P.S. This is my first question, I may have butchered the norm on how to ask proper questions. The reason I am asking this question is I am writing a program that fails when both sets are same and wanted to know what is the probability of my program breaking.
