Look at the multiples of 5 in the range: 5,10,15,20,25,30,35,40,45,50.
\n" ); document.write( "There are 10 of them.
\n" ); document.write( "Look at the multiples of 6 in the range: 6,12,18,24,30,36,42,48
\n" ); document.write( "There are 8 of them.
\n" ); document.write( "Look at any number that is both, so you don't count it twice: 30
\n" ); document.write( "Between 5 and 50 there are 50-5+1=46 total numbers.
\n" ); document.write( " $\"P%285%29=10%2F46\"$
\n" ); document.write( " $\"P%286%29=8%2F46\"$
\n" ); document.write( " $\"P%285_and_6%29=1%2F46\"$
\n" ); document.write( " $\"P=P%285%29%2BP%286%29-P%285_and_6%29=10%2F46%2B8%2F16-1%2F46=17%2F46\"$
