Hi,
\n" ); document.write( "*Note: The probability of x successes in n trials is:
\n" ); document.write( ".
\n" ); document.write( "P = nCx* \"p%5Ex\"*\"q%5E%28n-x%29\" where p and q are the probabilities of success and failure respectively.
\n" ); document.write( ".
\n" ); document.write( "nCx = \"n%21%2F%28x%21%28n-x%29%21%29\"
\n" ); document.write( ".
\n" ); document.write( "Question states p(teacher drawn) = 5/25 0r .2 and q = .8
\n" ); document.write( ".\r
\n" ); document.write( "\n" ); document.write( "A.
