\n" ); document.write( "The total number of ways of choosing 6 of the 10 cards is

\n" ); document.write( "\"C%2810%2C6%29=210\"

\n" ); document.write( "The number of ways of choosing 3 of the 5 cards in each suit is

\n" ); document.write( "\"C%285%2C3%29%2AC%285%2C3%29=10%2A10=100\"

\n" ); document.write( "ANSWER part a: 100

\n" ); document.write( "By symmetry, the number of ways of getting more hearts than spades is equal to the number of ways of getting more spades than hearts. So the number of ways of getting more hearts than spades is

\n" ); document.write( "\"%281%2F2%29%28210-100%29+=+55\".

\n" ); document.write( "ANSWER part b: 55

\n" ); document.write( "Note we can find the answer to part b with more straightforward methods.

\n" ); document.write( "4 hearts and 2 spades: \"C%285%2C4%29%2AC%285%2C2%29=5%2A10=50\"
\n" ); document.write( "5 hearts and 1 spade: \"C%285%2C5%29%2AC%285%2C1%29+=+1%2A5=5\"

\n" ); document.write( "More hearts than spades: 50+5 = 55

\n" ); document.write( "
\n" ); document.write( "
