There are two vowels in the first 8 letters of the alphabet (a and e). Since
\n" ); document.write( "these two letters must be included in every word, we must select 3 additional
\n" ); document.write( "letters from the remaining 6 consonants to get a group of 5 letters.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "There are \"C%286%2C+3%29+=+6%21%2F%283%21%286+-+3%29%21%29+=+20\" ways to do this, so there are
\n" ); document.write( "20 different five letter groups.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "For each group, the five letters can be arranged in 5! = 120 ways.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "The total number of \"words\" is then:\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "(120 words per group)(20 groups) = 2400 words\r
\n" ); document.write( "
