Answer:
The number of distinct arrangements is 12600.
Step-by-step explanation:
This is a permutation type of question and therefore the number of distinguishable permutations is:
n!/(n₁! n₂! n₃! ... nₓ!)
where
In this case
Therefore,
Number of distinct arrangements = 10!/(4! × 3! × 2! × 1!)
= 12600 ways
Thus, the number of distinct arrangements is 12600.
