Welcome to your interview.
The question is on your right: Probability of All Faces in Six Rolls. 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.
We roll a 6-sided die n times. What is the probability that all faces have appeared in some order in some six consecutive rolls?
