How many ways can four people be arranged in order of height from shortest talkest

To find how many ways four people can be arranged in order of height, we need to determine the number of possible permutations of four distinct individuals.

The formula for calculating the number of permutations of \( n \) distinct objects is:

\[
n! = n \times (n-1) \times (n-2) \times \cdots \times 1
\]

In this case, \( n = 4 \), so the calculation is:

\[
4! = 4 \times 3 \times 2 \times 1 = 24
\]

Therefore, there are **24 ways** to arrange four people in order of height from shortest to tallest.
