Using multiplication principle what is the number of 3-letter words that can be formed ?
Expert Answer
We have to find the number of ways in which a 3-letter word can be formed using multiplication principle
Multiplication principle says if there are m ways of doing one thing , n ways of doing other , then total number of ways would m times n
As we have to find the number of ways to form a 3-letter word
Here we are considering that repitition of letters is allowed
so we can say that first letter could be an...
