How many six-letter words (not necessarily with sense) composed of 4 different consonants and 2 different vowels can be formed from the English Alphabet?
Are you allowing repeating of the letters? By sense are you allowing "cdvowu" as a word? if those were your 6 letters? Are you wanting to know all possible combinations or just for those specific 6 letters?
so i had answered this, and then realized this poster had put all of their assignments on here, without thinking about them or attempting to do them. so, i'll help after diceyfume shows us his attempts at solving this problem and his thought proceses.
