I had a MCQ exam today. 90 Questions with 4 alternatives. I need help calculating my chances of passing (which should be really small).(adsbygoogle = window.adsbygoogle || []).push({});

I know 3 of my answers are correct. I gambled on the rest.

Also, please calculate the chance of passing, assuming that my guesses were a little more educated, so that the chance of hitting the correct answer was 1/3 instead of 1/4.

I need 36/90 correct to pass.
