40 tiles

Assuming the vowels and non-vowels are equal to the five picked, there would be 40 tiles that are vowels.

You have picked five different letters. 5% or 1/20 of 100. If two of those five were vowels, then if you consistently pick 2/5 vowels every time, a predicted 40 tiles will be vowels, 60 would not.
