- Dividing 100% by 3 without any left - Mathematics Stack Exchange
So in mathematics you can divide $100\%$ by $3$ without having $0 1\%$ left $100\% 3 = 1 3 = \frac13$ Imagine an apple which was cloned two times, so the other 2 are completely equal in 'quality' The totality of the 3 apples is 100% Now, you can divide those 3 apples for 3 persons and you will get 100% divided by 3 and none left

- Law of Iterated Expectations example - Mathematics Stack Exchange
Denote: Y = the second guy's earnings X = the first guy's earnings Now, let's prove that E (X) = E (Y), using LIE (law of iterated expectations) E (X) = 2 3 * 0 + 1 3 * 100 = 100 3 E (Y) = E (E (Y|X)) = prob (X=100) * E (Y|X=100) + prob (X=0) * E (Y|X=0) prob (X=100) = 1 3 E (Y|X=100) = 1 2 * 0 + 1 2 * 0 = 0 prob (X=0) = 2 3 E (Y|X=0) = 1 2 * 0 + 1 2 * 100 = 50 Substitute these numbers into
