    I typed the necessary information in multiple times ans the expected value result did not change from zero. i am very frustrated at this. take this website down if you’re going to advertise something that seems great but doesn’t work. ridiculous.

    Did you hit the “calculate expected value” button? You need to do that otherwise it will stay at zero.

    Hello, Paul,
    It works fine for me (I tried it in IE and Chrome), so I’m stumped. If you could let me know what your inputs are I will see if I can troubleshoot.
    Regards,

    Nice job with the temp. fix on the calculator, glad to see a website that genuinely is trying to help people with a format that doesn’t look like it belongs in ’02. Keep up the good work.
