\n" ); document.write( "\n" ); document.write( "(n C k)*(p)^(k)*(1-p)^(n-k) ... n C k is found through the combination formula (n!)/(k!*(n-k)!)\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "(7 C 2)*(0.28)^(2)*(1-0.28)^(7-2)\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "21*(0.28)^(2)*(1-0.28)^(7-2)\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "21*(0.28)^(2)*(0.72)^5\r
