You can put this solution on YOUR website!
For the middle to contain 60%, then the tails must contain 40% total or each must have 20%.
\n" ); document.write( "So find a such that $\"P%28a%29=0.2\"$ then you'll know that $\"P%28a%3Cx%3C-a%29=0.6\"$
\n" ); document.write( " $\"P%28a%29=0.2\"$
\n" ); document.write( " $\"a=-0.84162\"$
\n" ); document.write( "So,
\n" ); document.write( " $\"P%28-0.842%3Cx%3C0.842%29=0.6\"$ \n" ); document.write( "
