1. is NO, since it states a probability is negative. p(A')=1-p(A). That means 4 is also NO.
\n" ); document.write( "2. TRUE.
\n" ); document.write( "3. NO, it is over time, which means 5 is TRUE.
\n" ); document.write( "6. TRUE, expected values are averages over time.
\n" ); document.write( "7. NO. A fair game has expected value 0, neither gain nor loss. \n" ); document.write( "

\n" );
