\n" ); document.write( "Hi
\n" ); document.write( "Note: The probability of x successes in n trials is:
\n" ); document.write( "P = nCx* \"p%5Ex%2Aq%5E%28n-x%29\" where p and q are the probabilities of success and failure
\n" ); document.write( "respectively. In this case p = .60 and q = .40
\n" ); document.write( "nCx = \"n%21%2F%28x%21%28n-x%29%21%29\" n = 20 and x = 10
\n" ); document.write( "P(>10 passing out of 20) = .7553 = P(11) + P(12)+...P(20)
\n" ); document.write( "for example:
\n" ); document.write( "P(11)= 167960(.6)^11).4)^9 = .1597 | 20C11 = 167960 \n" ); document.write( "
\n" );
