I have just taken my first and last multiple choice test ever, because I live in Denmark. I think there is a high chance of me not passing because of my terrible memory, even though I have studied a lot.

But I am having a really hard time calculation the probability, I don't understand all the weird letters in the formula for it.

What is the probability of passing the test if you have to have minimum 60% correct out of 60 questions and every question have 4 possible answers(A,B,C,D).

Maybe there a calculator online where I can just put those numbers in? (Cool)
