all contain tomatoes
\n" ); document.write( "(7/12)(6/11)(5/10)(4/9)(3/8)=2520/95040
\n" ); document.write( "or 7C5/12C5
\n" ); document.write( "=0.0265\r
\n" ); document.write( "\n" ); document.write( "5 or more
\n" ); document.write( "6 would be the above (not rounded)*2/7=0.0076
\n" ); document.write( "7 would be that*1/6=0.0013
\n" ); document.write( "That sum is 0.0354\r
\n" ); document.write( "\n" ); document.write( "Exactly 3 is 10 (5C3)(7/12)(6/11)(5/10)(5/9)(4/8)=0.4419
\n" ); document.write( "or 7C3*5C2/12C5
