the proper formula to use on the following
\n" ); document.write( "at Least Once Problem:
\n" ); document.write( "meeting at least one left handed person in eight random encounters on campus when the incident rate is 11% (11 in 100 are left handed).
\n" ); document.write( "------
\n" ); document.write( "Binomial Problem witn n = 8 and p(left) = 0.11
\n" ); document.write( "----
\n" ); document.write( "P(at least one left handed) = 1 - P(no left handed)
\n" ); document.write( "------
\n" ); document.write( "= 1 - 0.11^8
\n" ); document.write( "-----
\n" ); document.write( "= 1 - 0.0000000214
\n" ); document.write( "======================
