how many three digit numbers can be formed from the set 0-9 if repetition are allowed and the number must be
\n" ); document.write( "a)even
\n" ); document.write( "--> the 1's digit must be 0, 2, 4, 6 or 8
\n" ); document.write( "Units is 1 of 5
\n" ); document.write( "Tens is 1 of 10
\n" ); document.write( "Hundreds is 1 of 10
\n" ); document.write( "---> 5*10*10
\n" ); document.write( "========================
\n" ); document.write( "b)divisible by 5
\n" ); document.write( "---> Units is 5 or 0
\n" ); document.write( "Tens is 1 of 10
\n" ); document.write( "Hundreds is 1 of 10
\n" ); document.write( "---> 2*10*10
\n" ); document.write( "======================
\n" ); document.write( "c)divisible by 10
\n" ); document.write( "---> Units is 0
\n" ); document.write( "Tens is 1 of 10
\n" ); document.write( "Hundreds is 1 of 10
\n" ); document.write( "---> 10*10
\n" ); document.write( "===============================
\n" ); document.write( "All assuming leading zero is acceptable, eg, 012.
\n" ); document.write( "If not, you need to specify that.\r
