To determine the number of combinations of 3 words, we need to know the total number of words available. Let's say we have a pool of n words. The formula to calculate the number of combinations of 3 words without repetition is n! / (3!(n-3)!), where "!" denotes factorial. This formula accounts for the number of ways we can select 3 words from a pool of n without repetition.
There are eight (8) different letters in that word, so that's the number ofletter choices you have in each 5-letter group without repetition.The number of different 5-letter "words" is (8 x 7 x 6 x 5 x 4) = 6,720 .(They don't necessarily mean anything. They're just distinct sequencesof 5-letters each, like Morse-code random practice groups.)

No there actually more combinations that we can make with numbers than letters. That's not actually true, since there are more letters than numerals, but every combination of numerals is a number and there are an infinite number of them, whereas, not all combinations of letters actually make words--there is only a finite number of words.
Seventeen Point Zero Fivei.e. 17 1/20I think you meant "How do you write 17.05 in words" - not "letters".
