We roll a fair die until we get a 4... (Probability Exercise 1.10)

Thanks a lot for this wonderful lecture. I thoroughly enjoyed seeing you go through the problem, and I genuinely appreciate you taking a pause and thinking through the way to prove why the product (5/6)ⁿ approaches 0. All in all, you should keep posting. You'll become a great math KZbinr one day!

The defenition of the limit is that u don't need to reach it, but can approach at a certain (small) perimeter and not go outside of the perimeter again with increasing n. Since 5/6 is a postive number u can't go negative, and each consequent number is smaller then the previous because u take 1/6 away of it.

Thats a great alternative proof by contradiction! Thanks for sharing (:

Thank you for the kind words! I will definitely keep posting and hopefully I will get better as time goes on.
