In how many ways can we choose 3 distinct letters of the  alphabet, without regard to order, if we must choose 1 vowel and 2 consonants?

Number  of possible  sets  of  vowels =  C(5,1)   = 5

 

Number of possible sets of  consonants  = C( 21, 2)   = 210

 

So......   5 * 210   =     1050    choices
