consider words of length 10 which only contain letters from the set {a,e,i,o,u,r,s,t,v,w}, suppose repetition of letters is not allowed.
\n" ); document.write( "1. how many different words of length 10 are there?
\n" ); document.write( "
\r\n" );
document.write( "10! = 3628800\r\n" );
document.write( "

\n" ); document.write( "2. how many different words of length 10 are there if the consonants i.e. r,s,t,v,w and the vowels i,e, a,e,i ,o, u must alternate
\n" ); document.write( "
\r\n" );
document.write( "They can be CVCVCVCVCV or VCVCVCVCVC [C=consonant, V=vowel]\r\n" );
document.write( "\r\n" );
document.write( "For each of those 2 types, there are 5! ways to arrange the consonants\r\n" );
document.write( "and 5! ways to arrange the vowels:\r\n" );
document.write( "\r\n" );
document.write( "5!×5!×2 = 120×120×2 - 28800\r\n" );
