Permutations with Repeated Letters | How Many Ways Can HEEDED Be Arranged? - SAT, ACT Math
In this video, we tackle a classic permutations problem:
How many ways can the letters of the word HEEDED be arranged?
We’ll break it down step-by-step, using simple explanations so you fully understand how to handle:
- Repeated letters in permutations
- The formula for permutations with repetitions
- Tricks to avoid common mistakes
