There are five vowels. Notice that any of the vowels could be chosen from 0 though 5 times in any given combination. We therefore need the number of combinations of 5 from 5 _with replacement_.
This is the number ( 5 + 5 - 1 ) choose 5 = 126.

Two make combinations you would take 2x1=2 combinations only

There are many five letter words with no vowels. Crypt, Cysts, Dryly, Flyby, Glyph and Gypsy are some examples. If you don't consider Y a vowel!
