Sorry for bad wording. Is the answer still 1/50? May14 comment Lottery Competition @RonGordon This is very badly worded indeed! Imagine such a lottery competition where lottery is bought randomly, independently and suppose we just know deal with probability that any person wins the lottery, and not even care or know the system of anouncing winner. Better still wording would have been "there is a quiz competition where there are 100 participants and the probability that they give correct answer is $x$, what optimum $x$ gives exactly two winners?' May14 asked Lottery Competition May14 comment Expectation Values $E[\frac{X_1+X_2 + ...+X_n}{n^3}] = n*E[X]$? Is this assumption always the case?
