\n" ); document.write( "Total number of 3-digit numbers, since the first digit can't be 0: 6*6*5 = 180

\n" ); document.write( "Number of even 3-digit numbers with final digit 0: 1*6*5 = 30 (since 0 is the final digit, we don't have to worry about possibly choosing it for the first digit, which would not be allowed)
\n" ); document.write( "Number of even 3-digit numbers with final digit 2: 1*5*5 = 25 (only 5 choices for the first digit, since it can't be 0; then any 5 of the remaining digits for the second digit)
\n" ); document.write( "Number of even 3-digit numbers with final digit 4: 1*5*5 = 25 (same reason)

\n" ); document.write( "Total number of even 3-digit numbers: 30+25+25 = 80.

\n" ); document.write( "P(even) = 80/180 = 4/9
\n" ); document.write( "
\n" );
