Welcome to your interview.
The question is on your right: Expected Rolls for D6 Game. Take a moment with it first.
Talk your thinking through with me if you like - when you're confident, submit your answer and I'll grade it like a real screen (7/10 or better passes). Discussion and graded submissions share your five interviewer interactions, so spend them well.
Roll a D6 until the result is divisible by n; what is the expected number of rolls?
