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(defective) = .1 & q = .9 
\n" );
document.write( "nCx = 
\n" );
document.write( "P(of six items two are defective)= 6C2(.10)^2(.90)^4 = .0984
\n" );
document.write( "P(of ten items, at least one is defective) = 1 - P(none defective)
\n" );
document.write( " 1-(.90)^6 = 1-.5314= .4686 \n" );
