Answer:
Step-by-step explanation:
We can select random 4 letters from the word LOGARITHMS in 10C4 ways.
For each of the selection, we will have 4! ways of arranging them. Like, if we end up selecting LATH from the word, we will have 24 words for this. So considering this, we will have 10C4*4! words i.e 5040.
