Question
Compute the number of ways you can select $n$ elements from $N$ elements for each of the following:a. $n=2, N=5$b. $n=3, N=6$$n=5 \quad N=20$
Step 1
This is a combination problem and can be solved using the combination formula $\binom{N}{n} = \frac{N!}{n!(N-n)!}$, where $N!$ is the factorial of $N$, $n!$ is the factorial of $n$, and $(N-n)!$ is the factorial of $(N-n)$. Show more…
