\n" );
document.write( "Note: The probability of x successes in n trials is: 
\n" );
document.write( "P = nCx*  where p and q are the probabilities of success and failure respectively. 
\n" );
document.write( "In this case p = .3  and  q = .7  and n = 12
\n" );
document.write( "nCx = 
\n" );
document.write( "P(2< x <9) = P(x > 2)- P(x ≥ 9) = .7455 - .0017 = .7438 \n" );
document.write( "
