In how many ways can the letters of the word 'LEADER' be arranged?

Problem restatement
Count distinct permutations of 'LEADER' considering repeated letters.

Given data

• Letters: L, E, A, D, E, R (6 letters total).
• Repetition: E occurs twice.

Concept/Approach
Permutations with repetition: total = 6! / 2!.

Step-by-step calculation
Total arrangements = 6! / 2! = 720 / 2 = 360

Verification/Alternative
If all were distinct, we would have 720. Dividing by 2! corrects for swapping the two indistinguishable E's.

Final Answer
360
