To find: number of words where L do not come together
Let the three L’s be treated as a single letter say Z
Number of words with L not the together = Total number of words - Words with L’s together
The new word is PARAEZ
Total number of words = \(\frac{8!}{213!}\) = 3360
Words with L together = 6! = 720
⇒ Words with L, not together = 3360 – 720 = 2640
There are 2640 words where L do not come together
