Different probabilistic statement for Simple Uniform Hashing
I was trying to understand the Simple Uniform Hashing assumption that people and books describe in works and make them into equations and realize which of the different equations are equivalent and which … Those are the equations and maths expressions I would use to describe uniform hashing. …

What is the formal analysis with Simple Uniform Hashing that the load factor is $\alpha = \f...
Recall the definition of the load factor is the average number of elements in a chain for hashing for a table $T$ of size $m$ (with $n$ elements in consideration). … In this case the definition of the load factor should be:
$$ \mathbb{E}[n_j] = \mathbb{E}[T[j]] = \alpha = \frac{n}{m}$$
I was wondering, why is the above statement correct under the Simple Uniform Hashing …

We want to calculate the expected length of a chain using SUHA (evenly distributed keys). Denote the length of a specific slot $j$ to be $N_j$. The length of this chain depends on how many of the $n$ …
