Find the z score for both times,
\n" ); document.write( " $\"z%5B1%5D=%2841-41%29%2F12=0\"$
\n" ); document.write( " $\"z%5B2%5D=%2861-41%29%2F12=1.67\"$
\n" ); document.write( "Then the probability would be,
\n" ); document.write( " $\"P=P%28z%5B2%5D%29-P%28z%5B1%5D%29\"$
\n" ); document.write( " $\"P=0.95221-0.5\"$
\n" ); document.write( " $\"P=0.452\"$ \n" ); document.write( "
