- Identify Total Permutations: Identify the total number of ways to arrange the digits without any restrictions.Since there are distinct digits, the number of permutations is factorial ().Calculation:
- Calculate Total Permutations: Recognize that the condition ＂ is to the left of ＂ divides the total permutations into two equal groups: one where is to the left of , and one where it is not.So, we take half of the total permutations to satisfy the condition.Calculation:
