there are 4 consonants 3 vowels how many 6 letter strings can u form with atleast one vowels in each

• 6 letter strings with atleast one vowel means possibilities are
  1) 4 Constants and 2 Vowels = 4c4*3c2 = 3
  2) 3 Constants and 3 Vowels = 4c3*3c3 = 4
  
  So the answer is 3+4 = 7

• 4 consonants + 2 vowel = 1*3=3
  3 consonants + 3 vowels = 4C3 *1 = 4
  
  
  so 3+4 = 7 strings are possible.
