The first tutor who responded perhaps misread the problem. His answer is the number of ways that the committee can be formed with EXACTLY 4 senators, which means 1 of the 14 representatives:
\n" ); document.write( "\"C%2812%2C4%29%2AC%2814%2C1%29+=+495%2A14+=+6930\"

\n" ); document.write( "But the problem says the committee must have AT LEAST 4 senators. So the earlier answer is missing the number of ways in which all 5 committee members are senators:
\n" ); document.write( "\"C%2815%2C4%29+=+1365\"

\n" ); document.write( "So the final answer to the problem is
\n" ); document.write( "\"6930%2B1365+=+8295\"
\n" ); document.write( "
\n" );
