Combinations of Three Words

Subject: Combinations of Three Words

I have three columns of 20 words each. I take one word from column 1, 
one from column 2, and one from column 3, and use them as a string. 
How many combinations are there?

Hi there! Well, if you have no restrictions (on re-use of words, for 
example), then the number of possibilities is simply 20 * 20 * 20.  
Hope this helps....
