What is the probability of getting at least one six on three rolls of a die?
Attempt: Since there can be one six or two sixes or three sixes on three rolls, I considered separate cases and added them up. So (1/6)(5/6)(5/6)+(1/6)(1/6)(5/6)+(1/6)(1/6)(1/6)=31/216, but answer is incorrect as per book.
What is the probability of getting at least one six in five rolls of a single fair die?

What is the probability at least one?

Is there a 7 sided die?
As one smoothly adjusts the size ratio between the sides and the faces, there will be a specific point where there is a transition between favoring the sides and favoring the faces. This intercept is the point at which the die is fair. Therefore, it is possible to have a fair 7-sided die.
