I tried to solve this problem:

*In a close answers quiz there are 8 items each of which can have 4 possible answers A, B, C and D and only one answer is correct.*

A quiz result is considered positive if at least 4 items have correct answers. What is the probability to get a positive result if someone answers randomly?

A quiz result is considered positive if at least 4 items have correct answers. What is the probability to get a positive result if someone answers randomly?

I made a small program which simulates the situation and I got about 0.113

Too bad I can't solve it using the formulas.

Any help will be appreciated

Thank you in advance
